Henrik,

Ah, I did briefly search the list archive, but hadn't come across your
earlier post, sorry.

I can confirm the conditions you outlined back then (ie. it's L-ALT+TAB, and
only that, that causes the problem, that on return to rterm I can use ctrl-C
to interrupt a running R call but then no further keyboard input).

Rather than remapping the key (just being lazy) I've found another
workaround -- a couple of taps on the left-ALT key whilst focus is on the
Rterm window seems to revive Rterm for me.

Thanks for the left-ALT tip. I hadn't noticed that the problem was specific
to this means of switching windows.

Cheers,

CB.
