Has anyone haved any problem with QB 4.00b?

I'm having a very strange problem with an IBM-AT and my program, that
is compiled with QB 4.00b. QB 4.00b is a version that I got directly
from Microsoft in Sweden because my QB 4.00 was making very strange
errors. I don't now how common QB 4.00b is.

I am using my program with an IBM-AT to read some PLC and a few other
instrument that measures flow. It all is in an chocolate factory.
The computer is standing by it's own and making day-, month- and
year reports. Once a week a person visit the computer to print out the
reports that is made last week.

Now the problem is that the computers just stops to work. The only way
to 'make it alive' again is to reboot the machine. When this happens I
loose all of the measurements, with the result that the reports isn't
to rely on. The stops always seem to happen at midnight.

I have my ideas that the problem could be with the QB 4.00b becasue of
all the problem that i have had with QB 4.00. I'm using 'ON TIMER' and
have a battery backup clock, maybe that causes something stranged. Or
could it be anything to do with the DOS version, now I can't remember
the version of the DOS. A nother thought that have occured to me is
that it maybe could have something to do with the extra ports. I have
4 extra ports besides the 2 standard (com1: and com 2:). And that some
kind of disturbanes occur on the line that makes the computer to halt.
The computer halts nearly once a month.

Please help me!

I have also interviewed the person that every week print out the
reports. He is not used to computers and all he does is the press the
right button and there after enters the date of the report that he
want to have printed. But hes saying that so far he can remenber the
time on the screen, I always print out the time and date, it shows
23:59. One minute to midnight. The strange thing is that my program
doesn't do anything special at midnight, that it doesn't do every
other full hour.

For the time beeing, while I'm waiting for your answers, I have
recompiled the program with QB 4.5 and taken away all the 'ON TIMER'.

             Thanks in the future, Urban Sp{nnar.
