To reproduce, visit Gmail - Click on Compose Mail - Now at the right of the page, you can click on the icon that opens the Compose Mail in a new window. That doesn't work currently in trunk builds. You don't get the Compose Mail page in the new window. The new window stays blank or is stuck with the 'Loading..' text. This works in 2005-08-15, but fails in 2005-08-16: http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=all&branch=HEAD&branchtype=match&dir=&file=&filetype=match&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=2005-08-15+08%3A00%3A00&maxdate=2005-08-16+08%3A00%3A00&cvsroot=%2Fcvsroot

This was indeed caused by the fix for bug 303267. If I pull by date just after that fix landed and back out the changes to nsGlobalWindow::GetLocation() the compose window works again. Oddly enoug the changes to that method were backed out by the fix for bug 304882, but something else apparently changed in (or between) those two fixes that makes the compose window still not work... Reassigning to mrbkap who landed those changes...

This would have been fixed by the checkin (currently trunk-only) for bug 304882, but the fiasco in bug 292731 caused this to stay broken, even after that check in. Now that that bug's fixed, I can no longer reproduce this one, marking FIXED.

This was also fixed on MOZILLA_1_8_BRANCH, marking as such (see comment 4).

Verified FIXED using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20050826 Mozilla/1.0 (SeaMonkey) and today's _trunk_ Ffox builds on Windows XP.
