Build Identifier: 20100218-1602

This popup just started to happen, I have been using eclipse for 2 months now and it just started today. It happens when I navigate to another class, save a class, open a different view, basically constantly.

Here is the log info

You mean the 'Package Explorer' or the 'Project Explorer'? Or another view?

Does the problem occur with 3.6?

Either, it happens when I scroll up and down in Package Explorer.

I don't know if it happens in 3.6. To be honest I find it hard to know which version I am on now. I can find the build identifier, but the version is another story.

You are using 3.5.2 based on the build identifier you provided in your original comment 0 (20100218-1602). Hence I asked if you would be able to reproduce it with 3.6.0.

Ok, thanks. Actually today the symptom is not showing up. Seems to have went away as quickly as it came. Yesterday I did bring down eclipse and back up, but the symptom persisted. Today not so (I have not rebooted/restarted my pc), so as of right now it is a non-issue. Weird, I wonder what caused this to start to show up?

Comment 6 Anthony Hunter

Can we get the detailed steps to duplicate the issue in Eclipse?

The issue is no longer happening. I have no idea what fixed it. The steps to reproduce are shown above, but I will list them again

Steps to Reproduce:
1. Open a java class
2. Select show in package explorer
3. Other scenarios also produce the symptom.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
