Stuck in full screen mode

I just installed emClient - was very happy with it until I tried to open a message in full screen mode.  The message was unreadable after that, I had to select it from the task bar to close it.  Now, every time I try to open a message, it opens in that mode - I can’t get out of it.  I tried to uninstall and reinstall the client with no success.  I am running Windows 10 and the version of emClient is 6.0.24144.0

Hi Noel,
could you perhaps take a screenshot of your problem? Unfortunately I’m having trouble replicating this issue or figuring our what it could be.
