[R] Rcmdr GUI goes into loop via alt+backspace under Windows OS

[tradenet]

Robert,

Alt+Backspace is a standard global shortcut key shortcut key for most
Windows programs (Word, Excel, Visual Studio, Notepad, Wordpad.  It is
equivalent to Ctrl+Z

It has been around since at least windows 98:

I wished alt+backspace performed the same action under Vista x64, or rang a
bell like it does on your machine.

Thanks for the feedback.

Regards,


Andrew
