Hate borderless windows with a vengeance - can't see where they start and end against other windows.

Also: Options+ failed so start (endless spinning) several times... turned out that an update might have been in progress... had to kill everything and let it restart. More info on what is happening required on the splash screen.

And, if I may, FFS I just wanted to check my mouse settings... should be a 10s task, not a 10 minute activity with debugging etc. KISS.
