Hello all,

of java code. The hint pops up and then i get the internal error message
stating that an SWT error has occured. In the .log file I see the
following lines:

You are running out of handles for your widgets
Seems like you have a seriouse handle leak in your app. Remember to
dispose any widget you created you no longer need.

I dont think that is the problem because I also get it when I start
Eclipse in a new workspace with just one class that contains an error.
When I click on the error in the margin the SWT internal error occurs.

Regs,

Peter

It's an OS thing. If you've run out of handles, and you start up a new app, that won't be able to create it either. If you see this same behaviour after a reboot, then yes, it's a problem with your code. If a reboot cleans it up, it probably just means there was a memory/SWT-handle leak that you're falling over with.

Win9x had a more serious problem with OS-handles than more recent versions of XP, so it would also be useful to know which OS you're experiencing this from.
