I have had similar issue when the shortcuts become corrupt either because someone deleted what a shortcut was pointing at or it simply had issue for no reason.  In my case I usually got an error though that kicked me out of Sage.  The fix was to delete the shortcut and recreate it.  In my experience when Sage appears to "lock" it is not actually locked rather the screen trying to open has lost focus and is opening on a monitor that does not exist or off the screen.   There is a Sage KB on resetting the positions of screens within the program if you think that may be the issue.  I can find it if you do not.  Thanks

Completely forgot to mention that I also did re-create the shortcuts and the error persists.  Thank you for trying to help.  I will look for the article, I think I know what you are referring to where it cascades all your windows??

This one is a bit different.  The windows are not cascaded they are simply gone and not capable of being brought back sometimes.  Here are two articles below.   I have found that, especially in remote desktop environments, you cannot move any Sage related screens off the main monitor.   If you do they will eventually "disappear" and make it seem like you are locked.  I advise everyone at my place to keep all Sage related reports, tasks, and screens on the monitor that is marked as Main within Windows.  it is tougher to fix a reg entry issue on a remote desktop server but the second article is profile related and easier to do in that circumstance.
