User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7a) Gecko/20040111 Build Identifier: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7a) Gecko/20040111 The page http://entries.the5k.org/1167/5k81.html will load fine. However, when you move your mouse back and forth over the flash object, Mozilla will either crash or freeze up. I've noticed this going back at least to 1.5 and an earlier version of flash. Reproducible: Always Steps to Reproduce: 1. go to http://entries.the5k.org/1167/5k81.html 2. move mouse over flash object Actual Results: Mozilla either crashed or frooze Expected Results: not crashed! I have win98se, flash 7.0 r19. Others on IRC have tried this page on winXP and win2k, yet had no problem, so this could be a win98-specific issue. I'll provide the talkback information when talkback builds are back.
Bug Day: 1-13-2004 Tested With: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7a) Gecko/20040113 I can confirm that this does NOT crash on Windows 2000
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6b) Gecko/20040102 Firebird/0.7+ Works for me, using Shockwave Flash 6.0 r79
Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7a) Gecko/20040112 Shockwave Flash 7.0 r19 tested with 1.4.1, 1.5, 1.7a: hanging, freeze I can save the page and view it locally, and it works fine: it is showing a circle inside a square made of 4 equal squares. Seen locally, the segments of this figure are rotating, when hovered, but always are connected to their originating position with one end. Seen on the website, there are segments spawned, changing place, and then after some time freeze. I checked systemresources in the tray, they were still reacting. No change on GDI, but System and User were decreasing as long as I clicked in the frozen flash, stopped, when I stopped, decreased after some clicks again. I was needing about 10 clicks to see a change, but this was reproducable, without counting. I installed 1.5 as this has talkback and tried, but only got a hang. Then I tried using 1.4.1 and got a hang that I had to use the reset key, Ctrl-Alt-Del wasn´t working. In the source of the file you can see that the CENTER tag ist misplaced: <center><object>.....</center></object> <HTML> <HEAD> <TITLE>5k81</TITLE> </HEAD> <BODY bgcolor="#000000"> <!-- URL's used in the movie--> <!-- text used in the movie--><center> <OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0" WIDTH=400 HEIGHT=400> <PARAM NAME=movie VALUE="5k81.swf"> <PARAM NAME=quality VALUE=high> <PARAM NAME=bgcolor VALUE=#000000> <EMBED src="5k81.swf" quality=high bgcolor=#000000 WIDTH=400 HEIGHT=400 TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash"></EMBED></center> </OBJECT> </BODY> </HTML>
Severity: normal → critical
Status: UNCONFIRMED → NEW
Ever confirmed: true
found reason: the misplaced <center>tag: on the website, hanging: <center><object>.....</center></object> changed by Save File As, working locally: <center><object>.....</object></center> changed by me, then hanging locally: <center><object>.....</center></object> So this is invalid code, but what can Mozilla do about this that it isn´t crashing on Win98? Saving the file corrects the bug.
Another thing to notice is that the original source is missing quotes around many of its attribute values, which Mozilla's 'save file as' fixes. 'Save file as' also eliminates <\embed>. The weird things is that on the website, you see a 10-by-10 square, but when you save it and view it, there's only a 2-by-2 square. Also, I managed to eventually crash IE 6 on the same page by moving my mouse around for long enough to fill up the big square with lots of those little segments.
I tried this again with Mozilla 1.7b. I can't get this to crash now, but instead Mozilla hangs.

Test URL now gone, how about a testcase, anyone?
Attached file The actual flash file
Fortunately I saved all my Mozilla testcases. (In reply to comment #5) > The weird things is that on the website, you see > a 10-by-10 square, but when you save it and view it, there's only a 2-by-2 > square. The testcase I just attached is back to having the original 10-by-10 square. What had caused the change (somehow) was having the flash file in a subfolder (bug230808_files\), which was created by Mozilla's Save Page As. I am no longer using Win98, but WinXP SP2. With Gecko 1.9 alpha1 and the latest Flash, 9.0.28.0, I no longer experience any crashes or hangs. Mousing over the squares does cause high CPU use, but I don't think it is causing any continuously growing memory use or other oddities. The crashes or hangs were only observed on Win98 and Linux. Win98 is no longer supported on the trunk. Could someone on Linux please check if any crashes or hangs still occur?
