Strange Eclipse UI Error [message #1718929] Sat, 02 January 2016 20:43 Go to next message

I get right down to the point.

Whenever I have two file editting windows open side by side and attempt to edit something inside of it I get an error window saying:

Unhandled event loop exception
No more handles

Then another window:

An SWT error has occurred.
You are recommended to exit the workbench.
Subsequent error may happen and may terminate the workbench without warning.
see the .log file for more details.

Been dealing with this for quite a while and have been able to avoid this problem by only having one file view and switching between tabs.
However, I get this problem if I try using debug mode.

Please Help!

That seems strange. Could you please provide more details, such as the Eclipse version (and where you downloaded it), OS version, and a detailed way to reproduce? And could you also try with a vanilla Eclipse (from download.eclipse.org), just in case it's caused by one of the plugins you have loaded.

Brian.

- Eclipse Mars.1 Release (4.5.1)
- Windows 7 64 bit
- Clean installed it a week ago (no plugins). I was using Eclipse Juno prior and had the same or a similar problem.

All I need to do is have two editors windows open side by side and attempt to interact inside one of those windows.

Screenshot of what I mean by two editors windows open side by side:

How long has your machine been up? (Have you tried rebooting your machine?)

Any tweaks to your .ini file?

Can you check your .log file?

I shutdown my computer daily and I haven't tweaked my .ini file.

I attached the .log file.

I did some searching in the bugs database and this sounds like bug 402983. The problem seems to be caused by some other third-party software running. There are some other culprits identified in this StackOverflow post too.

Thanks Brian I installed WindowBuilder and set that as my default editor and it fixed it.

It's weird though because I tried that a couple weeks back and it didn't work. O.o

But anyway thanks again! Smile
