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

[tradenet]

I'm using Rcmdr version 1.4-10 with R version 2.9.0 under Vista x64.

A standard editing convention under Windows is that alt+backspace is a
keyboard shortcut for "undo".  I often find myself hitting the [alt] and
[backspace] keys while editing scripts in Rcmdr. However, this causes the
Rcmdr GUI to go into a crazy mode where the menu keeps flashing and the GUI
is unresponsive.  Sometimes after several minutes, the GUI menus stop
sporadically flashing and the GUI becomes responsive again, but usually I
have to kill R.

Has anyone else seen this problem and might there be a fix for it?

If it weren't for the fact that the particular key combination is a standard
in Windows I would ignore the problem, but I often get trapped by it because
the GUI handles this standard Windows key combination is such a bizzare way.

I'd appreciate any suggestions you might have.

Regards,

Andrew
