[Evolution] Email previews not working properly

["Rachel Phillips" <varaonaid gmail com>]

Hi,

I'm new to Evolution and in the process of switching over to it completely and so far, I really like it.  But I'm having some strange behavior that I'm not sure how to fix.

When I first open Evolution, email previews in the bottom pane work perfectly.  But if I switch folders, such as from inbox to sent mail, previews stop working altogether.  If I switch back to the original folder it still doesn't work.  The only things that restore email preview is restarting the program or clicking on the "On This Computer" top level link/folder.  Then the preview feature is restored for the next folder I click on but I lose it again as before when switching to a different folder.

Is there anything I can do to fix this?  Is it a faulty install?  A bug?  An incorrect setting somewhere?  Any help you could give would be most appreciated!

Thanks so much in advance!
Rachel
