The web site http://www.trainingcamp.net causes the Mozilla Browser and all
other open windows tied to Mozilla to Lock/Freeze/Hang. However, it does not
cause Mozilla to actually crash/bomb/BSOD.

I can tell Mozilla tries to download/cache the flash animation, but once the
player kicks in, we have hang time. The page is just blank. No HTML to the page
has a chance to load. I also have a memory watching program (Release RAM)
loaded, with RRAM's CPU and Memory usage meters/bars in my system tray. While
Mozilla's hanging, Memory usage goes up 75% then quickly back down, then back
up, then back down, etc.

No other Flash based web pages do this, this is the only one I've encountered.

Flash Version: Shockwave Flash 6.0 r79
This maybe just a FlashPlayer issue, but thought I'd post it here just to be
sure. Maybe jscript? I've had the JavaScript Module cause Mozilla to perform and
Illegel Operation many a times, but I used the TalkBack program to report that
issue.
Here is the Info for that issue:
MOZILLA caused an invalid page fault in
module JS3250.DLL at 018f:610878af.

Reproducible: Always

Steps to Reproduce:
1. Open Mozilla Navigator/Browser (Quick Launch already loaded)
2. Go to the URL HTTP://www.trainingcamp.net
3. Wait a couple seconds/watch network activity on hub
4. Once you stop seeing network activity, Mozilla is frozen
Actual Results:  
Mozilla froze, I had to CTRL+ALT+DEL and kill Mozilla.
I then had to go back to this site and re-type all this info ;)

Expected Results:  
Loaded the Flash animation in the middle on the page.

No lock here, but the memory usage went nuts as seen from task manager. It would
zip back and forth between anywhere from 30MB to 200MB. It finally loaded and
memory went back to normal. WinXP Moz 2003062004

Confirming and changing the summary.

I tried it once again on my machine (512meg 1.2GHz) using the same Flash and
Mozilla version as originally posted, and waited 2 minutes on broadband, then
the page came up.

But one thing I noticed now that the page is viewable, other then the "erratic
memory and CPU usage", the Java Script or Applet running the Menu Links up above
the Flash Animation displays their Menus behind the Flash Animation (HOME, ABOUT
US, COURCES, etc). Thus you can't see the menu content.

The problem seems to have fixed itself (WinXP Moz 2003080304 Flash 6.0 R79).

No hang at all, memory doesn't go nuts, and page only takes about 15% processor
usage (which I'm assuming is normal for a Flash animation?).

How does it work for you, Curtis?

Ahh... Yup, seems to load nice and speedy now. I didn't change a thing on my
system. Still using Win98SE, Flash 6.0 r79, Mozilla/5.0 (Windows; U; Win98;
en-US; rv:1.4) Gecko/20030624.

Maybe the webmaster tweeked something?

However, even though this may have to do with their website, the menus don't
work. The Java Script or Applet running the Menu Links up above the Flash
Animation displays their Menus behind the Flash Animation (HOME, ABOUT US,
COURSES, CORPORATE TRAINING, etc). Thus you can't see the menu content.

If the menu continues to be a problem, file a new bug. Marking WFM.
