That is not a problem of jEdit or something you could fix with jEdit config. It is windows that gets "confused" with more than one monitor. I saw, for example, that if I sent my laptop to sleep and wake it up again without the 2dn monitor the desktop looks really wrecked: all the applications are resized and many have "forgot" child windows on the other monitor.

long life to X-Windows

It is a problem of both. jEdit should test the screen size and move all windows that are out of the normal screen back to the main window. This are only some lines of code. That XP do not handle this stands on another page...

Is there any way to fix this without messing with display settings? I "lost" my search window in my 2-laptop configuration at work and nothing would get it back (restarting jEdit included). Luckily I brought my laptop home and connected it to a monitor where the lost window appeared when summoned (Ctrl+F)! However, this solution won't work for everyone who encounters this issue. In my case, neither display (at work or home) could be made any larger, so I was just lucky that the search window appeared when I asked for it.

Is there some file in the .jedit or program folder that handles window positions? If so, would deleting it resolve this?

Please, see there.
