MacOS 8.5.1; Mozilla M5 release While loading pages, resizing M5 and/or popping up other windows over it cause its user interface to repaint incorrectly, and the app to get in an odd state. Sometimes it even locks up the OS (isn't MacOS grand), and I have to kill it with macsbug to continue. Steps to reproduce: 1. Visit a website that takes a while to load due to gratuitous use of graphics and/or tables (eg, www.slashdot.org) 2. Rapidly resize browser many times, and put other windows in front of it, then pop M5 window back on top. 3. Repeat 2 several times before page loads. Eventually you will see problem. It always happens for me if I am persistent. I hope this is not a duplicate bug report. I am unable to search in bugzilla with my other browser (Navigator 4.05 on Macintosh) as I get a javascript error in the bugzilla search page when I use the "product" and "component" list boxes. It says "undefined is not defined" (I should certainly hope not!).

Don, can you tell whether this one is a duplicate bug? If not, I think it should belong to your team. Thanks!

Putting on [PP] radar.

David, can you cause this to happen? Any idea whose bug this really is?

I can't reproduce but this could be a timing thing where it will happen all the time to people on either slow or fast computers. Sounds like either a toolkit or a layout bug.

claudius, we could some testing help/talkback analysis on this one. If we can come up with a stack trace and reproducable test case we aren't going to make much progress. pulling off the M6 radar..

reassigning to pinkerton, cc evaughan. What I'm seeing is just the content taking forever to load. The chrome looks fine, and still works, but the page never finishes loading.

Just to be clear, I did not see a crash (PB3400, 8.6). I broke into the debugger to get a stack trace, but could be just the normal rendering of the status bar.

This sounds _a lot_ like bug 5949. Can the original reporter verify if this is a duplicate? If I haven't heard in a week or so, I'll mark it that way since it sure sounds exactly like what I reported a few weeks ago to pierre. cc'ing pierre as well.

Correct: it's a duplicate of #5949. I'm going to work on it tonight. *** This bug has been marked as a duplicate of 5949 ***

VERIFIED dupe...and it's fixed too!
