I can see the variables in the debugging pane, but can't access them or stop the app. I have to use Task Manager to kill the Java process, which then allows me back into JBuilder. The same problem does not occur if I run the app normally. Can anybody help me, or should I look at upgrading my JBuilder?

If you have, good. If you haven't just wait... They seem to have disappeared off the Borland website. I'm tracking that down now. On a version of JBuilder that old, you are unlikely to get any new bugfixes or patches if this turns out to be unfixed by the current patches. You could always download the current version of JBuilder, and try it out to see if this problem exists in the new version. If it does, then you can make a bug report in Quality Central. To report a "hanging" problem like this, you need a thread dump. On Windows, you get this by running JBuilder.exe (instead of JBuilderW.exe) which gives you a console window (just like java.exe vs javaw.exe). Then, repeat the steps to duplicate your problem. When you reach the "hang", you can produce a thread dump in the console window by typing "Ctrl-Break". Then you can post that dump. Posting a whole project, including the steps needed to duplicate this problem would be even better. -- Regards, Lori Olson [TeamB] ------------ Save yourself, and everyone else, some time and search the newsgroups and the FAQ-O-Matic before posting your next question.

Eoin The only one of these newsgroups that allows attachments is the borland.public.attachments group. But I wouldn't post it there. This sounds like a bug, not just some settings problem.
