I have an old DOS app that runs off a NW6.5 server. It occasionally
locks as it loads, but if left alone for a considerable period, will
eventually load correctly.

It always hangs at the same point, and Monitor shows what files it has
open at that time. However, when we try and spot what happens on a
normal load, the files that are opened and closed as the app opens zip
by too fast to see what they are.

My question is whether or not there is any way to capture or log this
output so as to see exactly what files get touched as the app opens?
This might help me figure out what it chokes on. <g>
