I've got a program written in VFP 5. It has one form with a timer.
On every tick of the timer, it checks the entries in a directory, and
adjusts some DBF tables.

In NT Server 4.0, it works fine and runs forever.
In NT Server or Workstation 3.51, the program gradually consumes more
and more memory until NT runs out of paging space and locks.

Any ideas why this would be?
