454104 - After loading this page, every click-and-hold drags the browser window

Status: RESOLVED DUPLICATE of bug 431902

(Firefox :: General, defect)

Description

[Chris Johnson]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10_5_4; en-us) AppleWebKit/525.18 (KHTML, like Gecko) Version/3.1.2 Safari/525.20.1
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-US; rv:1.9.0.1) Gecko/2008070206 Firefox/3.0.1

After going to Desktop Tower Defense, every click-and-hold in the same browser window causes the entire window to be dragged.  As a result, one can't select text, drag images to the desktop, drag scroll bars, etc.

This behavior persists even after you leave the DTD page.  It also holds for any other tabs in the same window that DTD was initially loaded in.  However, new windows do not exhibit this behavior

Reproducible: Always

Steps to Reproduce:
1. Go to the above URL
2. (Optional: do other stuff in the same window - got to other pages, open new tabs, etc.)
3. Click and hold anywhere in that window.
4. Move the mouse while holding.
Actual Results:  
The window moves with your mouse.

Expected Results:  
Depending on the context: text could be selected, an image could be dragged, a scroll bar could be dragged.

If you try to drag an image, you get the normal image dragging behavior: you get a semi-transparent, hovering, possibly scaled down image under the cursor.  However, when you move it, the window moves too.  So, you can sort of drag images, but you can't drag them out of the window.

As best I can tell, this is a dup of bug 431902.  But this bug has a
better (simpler) example.

This bug (bug 454104) tries to load a Java applet, which fails to load
because it's only compatible with Java 6 and higher.  Bug 431902 loads
a Java applet that dies shortly after loading.

With both bug's examples, you see repetitions of the following error
in the system console:

*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug

Neither bug happens with Firefox 2.  Neither bug happens on OS X
10.4.X (only on 10.5.X).

I'll try my "fix" for bug 431902, to see if it also fixes this bug.
