Problem with the verify.

Last week our programmers attended a class where we all verified programs
using the Verify option in the Source menu. This week, three of us could no
longer verify programs, but one of us still can. (I've asked all programmers
to try and let me know who can and who can't.)

For those of us who can't verify, here's what happens:
We take the option, and a delay of several seconds occurs where nothing at
all changes on the screen--no status bar or status message, nothing. If you
look at the task manager, WDSCi is using about 90-99% of the CPU during this
delay. Then the status bar finally comes up. The status bar runs endlessly,
and WDSCi is using significant CPU, but the verify never ends. One
programmer let the verify run for 20 minutes to see if it would end. Hitting
the cancel button on the status bar does not end the verify. We have had to
kill the WDSCi process manually using Task Manager.

We have not changed anything from last week to this week on our PCs.

Any ideas?
Thanks,
