Description Ed Merks

For M5, when I open a editor, the area doesn't paint.  I have to resise the editor area.  Views seem to have the same problem; I couldn't figure out why my properties view wasn't working, but it was just a paint problem.  This makes the IDE practically unusable.

We haven't had similar reports from other people, Ed. Does it work with M4?

I'm guessing 3.8 functions properly for you, correct?

Comment 2 Ed Merks

It's only a problem with 4.2M5 not with M4 and not with 3.8M5, but now that I've restarted Eclipse, it's working properly again. The disappearing debug toolbar issue seems similarly transient...  Perhaps some exception triggers the behavior, but there seem quite a few of those that I start ignoring them.

You've seen bug 348429 before.

And your other problem is bug 370500.
