Labview program stops running correctly after computer is switched on one hour

[Martien Janssen]

Hope to get help on this strange problem.

I have a Labview program (executable using a run time version) running on a
portable computer (Dell Inspiron 4000 with Windows ME) which collects
measurement data and stores these to a file over a long time period. When I
start up the portable and then start my Labview program, the program fails
to work correctly exactly one hour after the portable has been started (in
fact, the program remains active but stops collecting and writing data).
However, if I start this Labview program just after that the portable has
already been active for one hour, the program is not interrupted and
continues to run for hours without any problems.

Obvi
ously, I have switched off all power management, screen savers, virus
scanners etc. to avoid interference of these, but without success. I have
run the same Labview program without any problems on a different Windows ME
system. Also on Win98 or 95 systems I have observed no problems. Does anyone
have a tip to which program or process could be activated in Windows ME
exactly one hour after the computer has started up and which might interfere
with Labview applications (when I look at all tasks running under Windows ME
I don't have an idea where to look at first).

Thanks in advance,

Martien

Did you shut off power management in the BIOS setup also?
Sounds like something is scheduled to go to sleep at 1 hour,
either the serial port or hard drive?
