Right click on Eclipse "Project Explorer" doesn't change focus
===

I'll start by saying that everything was fine until I had some system problems a couple of days ago and my machine froze.  A reset corrected that, and then I upgraded my VMWare, which insisted that I bring Eclipse down first.  Not sure which of those screwed things up.

I'm in the source panel editing the source for an Android project.  I save, then right click the project in the Project Explorer panel expecting to select Run As and pick the run mode.  Instead, the Panel Explorer doesn't take focus before popping up the menu, so I get "Run Configurations" only.  Also, I can't double click a source file and pop it up without first clicking the Project Explorer panel header first to switch the focus.  

Anyone seen this before? I'm guessing there's some setting file that got corrupted.  The interruption in workflow is driving me nuts.  Help!
