Some questions:
1) are you saying in the OP that you have *two* SC icons in the system tray?
2) how did you update SC?
It sounds to me like you
might have the portable version and the installed version running at the same time - both starting with windows.
(Or, was there a bug a while back with two instances of SC running?)
If you have two icons in the tray, via right-click check the 'About' for each to see if they the same version.
- For a quick fix, just right-click one and exit it. The other should work then.
- For a medium fix, make sure only one started with windows (via preferences).
- For a proper fix... do you have dcupdater installed? I have ideas - but it's possible it is a bug so maybe wait see what mouser says.
