Since it fails when deployed from D5, I suggest fixing it there before
moving to D6.

What does the program do? That is not intended to pry into your
intellectual property; generic answers will be helpful. In particular,
does it use COM, sockets, ODBC, etc.? I found it necessary to tweak the
idle loop in some versions, particuarly so when I was still relying
heavily on COM. The failure mode was something like what you describe.
Searching Ian's archives might help. Look at D4's idle loop and compare
what 9x would do there vs. in D5/6.
PLEASE make a backup before making any changes. Having done that, you
might alter the D5 idle loop accordingly to see if it helps.

Just out of curiosity, why is the customer sticking w/ 98? I agree that
since they are, you should do your best to target it. You might be
surprised to find who shares that goal:

Do you mean hardware and software? Hardware requirements for Dolphin
have never been terribly demanding, so I doubt that is the problem. I
would look at the idle loop. You might need to hack in a test for 9x
and then re-establish the D4/9x WaitFor*() call. Again, please make a
backup before trying it.
Another possibility: do your users pop up menus and then walk away? If
so, and if you rely heavily on deferred actions, you might need to look
at Steve Waring's(??) view queue goodie.
Have a good one,
Bill
