'Invalid output directory.' error

2003-12-19 06:09:41 AM
I am running the developer version of JBuilderX on an P4, 2.8GHz machine
w/2Gb RAM and Windows XP.
I get an 'Invalid output directory.' error almost once every day now when I
try to build my software. I can't find a pattern to when it happens but I
notice that my project's '/classes' directory is locked and unavailable to
me from Windows Explorer.
Restarting JBuilderX does not solve the problem and I have to reboot my
machine. Then everything is fine again.
Has anybody else had this problem? Any help would be gratefully appreciated
as this is very frustrating.
Thanks in advance.
