Hello
The problem seems to be solved (more or less). It only occurs
if the application is started from a network drive and the
connection to that drive is cut.
I'm not sure where the problem is exactly but all other accesses
to the network do not result in this kind of desaster.
Anyway: Not a problem of ICS anymore.
Thanks (especially Arno)
