Hi Paul. I must admit that it's been some time since I even tried debugging a GUI application (6 months?). Since then, I've migrated to emacs 21.1, at least 2 versions of jdee, and applied multiple windows updates.
This morning, I wrote a trivial swing program and fired up the debugger. Of course, everthing works fine now. (both launching and attaching to an existing process). Emacs no longer freezes when i hit a break point on the event dispatch thread. I've changed something in my environment, but I can't be much help in telling you what. Maybe somebody who is experiencing the problem can incrementally upgrade and nail down where the problem is (was). My current environement: MS Windows 2000 5.00.2195 Service Pack 2 Emacs 21.1.1 JDEE 2.2.9beta10 jdk 1.3.1_01 -jim > -----Original Message----- > From: Paul Kinnucan [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, October 16, 2002 12:26 AM > To: James Cox > Cc: [EMAIL PROTECTED] > Subject: RE: Re[2]: JDEbug hangs trying to debug GUI (swing) > application > > > James Cox writes: > > I too experienced the same problems that Serguei did when > my app hit a > > breakpoint while on the event dispatch thread.
