[Xitami] Assertion failed

[Gary Rumble]

I keep getting an Assertion Failed message.  The complete message is:
Assertion failed sfldate.c line 623 iMatix\Work\products\xitami-25

I'm running 2.5c2 on Windows 98 in a lightly loaded system.

Any ideas?  It keeps crashing several times a week.

Thanks, Gary
