thank you, but that did not help. everytime i launch the emulator
application i get stuck with an older version of a perviosuly installed app
on it whihc doesn't run corretly. I have to do a "New Session" each time i
get in there, because by default the older "buggy" program is running. I
need to stop this somehow, it odesn't matter if i download a new version of
the emulator and run the executable, i still get that program running.

----------
Greetings, in the settings of the emulator, there is an option which allows
the emulator to save the session: never, always, ask user. It's under
properties. That might be what you first problem is. Concerning the 2nd
issue, I'll let the more experienced developers deal with it.
Kind regards,
