I have had very similar behaviour:
Starting ‘aptitude’ from within screen results in no visible change
except that the cursor is repositioned to the home position (top
left). Everything that was on the screen before starting the program
remains unchanged.
No further interaction appears to have any effect, *but* when I press
‘q’ then ‘y’ (request Quit to aptitude, then confirm), the screen
again responds as though I had never run aptitude — or, as though I
*had* run aptitude and then quit back to the shell.

I had this behaviour since early in the Lenny cycle, but only
sporadically.

Likewise, I have only ever been able to reproduce this on one
particular host. Yet I keep my configuration files for screen (and
most other programs) synchronised between hosts.
One recent change I have made, which was not done with this bug in
mind, but AFAICT has never been followed by a recurrence of the
problem, is to set the following option in ‘.screenrc’:
# Enable VT100 alternate screen buffer support?
altscreen on
This would at least seem to be related to the problem, but doesn't
fully explain the erratic nature of its reproducibility.
