flash9f.ocx crashes

Has anyone experienced random crashing on their Flex apps after long
usages?  One of my apps is causing IE to shut down after running for a
few days -- it's a kiosk-esque app, so it does commonly run for an
extended period of time.

The error from the Application event log:

Faulting application: iexplore.exe, version 7.0.6000.16608
Faulting module: flash9c.ocx, version 9.0.45.0
Fault address: 0x0000286f

I've been able to reproduce this on two machines (both Pentium Win XP
SP2 boxes) with varying versions of IE and Flash9*.ocx.  

I've found a few reports of this happening to other applications.
Re-installing the Flash Player has "sometimes" fixed the issue, but
nobody is able to tell exactly what is causing the problem -- Is it
something specific in the application?  Something with the Flash Player?
Something with Windows XP/IE?  

Has this happened to anyone else on the list?  Did you find any
information on a reliable fix?

Thanks!
