Moving to Platform
Moved it how? Was it a minimized view that you opened (so on top of the other views in the workbench)? Also. please attach your .log file, <workspace>/.metadata/.log PW

I just dragged the project explorer to move to top. But the project explorer disappeared and the shadow is not closed. I reset the view.But still it occurred. Please check the attachment for the error log.

As a workaround, you can shut down eclipse and then remove the <workspace>/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi file (back it up first) PW
From the screen cap it does appear to be a leftover composite from an open minimized stack. I just tried closing the last view in a minimized stack on my current install and it seems to work OK. The problem occurs if you *drag* the last view out of an opened minimized stack...we should be either checking this or ensuring that the stack that we're dragging *from* is not minimized.
BTW, this is a transient SWT element and is not in the model so a simple 'restart' should fix it up.
Ya after restart it is fixed. But i don't know why this happened. So only posted the bug.
Yes, it was a good pickup actually...it's certainly a bug. Basically it's my code for the minimized stack handling that's the root cause.
Eric, here are some reproducible steps. I was able to reproduce in 4.2.2 and 4.3 PW Launch Eclipse with a new workspace (as it will become unusable in a few minutes) In the Resource perspective, create a new Project Create a new File (test1.txt) Create a new File (test2.txt) Double click on the editor tab for test1.txt to maximize it Click the minimize icon on the editor toolbar > Now you have a problem, because the editors did not go back to their correct location -- using the Restore button in the editor toolbar has no affect -- closing the editors leaves an unusable area on the screen that cannot be recovered (see screen capture) -- Reset Perspective has no affect -- sometimes restarting the workspace seems to get things working again (though not always) -- sometimes the NPE below can be found in the Error Log (though not always)
Moving to 4.3.1 this is a slightly different issues than the one Paul describes below...
This is still there and we should fix it...it should just be a matter of fixing up the listeners for the trim stack to manage the 'remove' caused by the drag...
Committed: http://git.eclipse.org/c/platform/eclipse.platform.ui.git/commit/?id=c59a25a972bf86c7ab37482b37cdf53774e14c69 This removes the MINIMIZED tag from the element being dragged *before* completing the drop operation. This was actually an issue where the dragged element was the MPartStack that was minimized. Even in the given scenario when you drag the only tab item in a stack it's treated as if the stack itself was being dragged...

Verified in 4.4.0.I20130915-2000. Paul, I also can't repro your steps of minimizing a max'd editor area, I think that was already reported / fixed in another defect.
