New window bugs
Date: October 02, 2001 05:07AM
New windows often open up in unpredictable places. Sometimes they cascade, sometimes they don't. It generally happens after using multiple windows... when you switch to another window then open up a new window, that window often pops up around the upper left corner or in the center of the screen.
It's a weird bug, but would be nice if it were just as predictable as NS4 (or even IE) is.
