still nothing as plausible as the rdpclip....
How "reliable" is getting the hang in at least one machine in 3 days running?
Are those machines bolted tight against user stupidity ?

If answer is in the realm of "pretty good", first I'd try shooting in the dark with a C++ timer (around here somewhere)
***after*** adding either coverage or logging - depends on how much data is gererated.

update:
move the timer action code away from interacting with your forms, displyaing the time info in
wait window nowait noclear
for test purposes a couple of days if possible. /update


Then move all similar code into calls in other ***proccesses***, if possible
- automating a player if such is available (never looked if one sports an interface)
