Hi KevinUshey, I upgraded to RStudio 1.1.4683.
After restarting RStudio a hundred times, I have a better method for "breaking" the interface.
Situation Setup
delete %localappdata%\RStudio-Desktop folder
Open RStudio.
(Mouse action) File->NewFile->New R Script
(note the cursor in the Source pane)
ALT+F
Down arrow 1 time to "New Project..."
Esc
Esc
(note the cursor returning to the Source pane)
(Now to break things, repeat a second time)
ALT+F
Down arrow 1 time to "New Project..."
Esc
Esc
At this point the cursor does not return to the Source pane.
And from this point on, clicking the mouse into the source pane, then pressing ALT-F and Esc Esc will not return the cursor either
