FWIW, I also have issues with Ctrl-W in the class and form editor. A lot of times pressing Ctrl-W will NOT save the active class/form changes although it closes.
I suspect this is related to the same issue as the Ctrl-S injecting of characters. VFP is not getting the key combinations correctly or in the wrong firing order which causes this munged up behavior.

>>Okay, so I am not the only one with this occurrence. The !! insert into my code upon saving, or rather, specifically using CTRL + S, also happened at my last full-time job. It is not only my computer.

>I use Ctr+W. I notice, that it saves and closes the form, but it also puts some character (like a square box) into the command window.
