Notes 6.5 crash while shutdown

Good morning,

we have an issue with one 6.51 Notes Client

(W2KSP4) in our company.

With version 6.3 (and earlier) we got a red error-box and with most of the clients this problem was solved after updating to 6.51.

But at this one there is no red box anymore, but the client crashes completely.

Also a complete Notes-Reinstall did not solve it.

Does anyone have the same problem and nows any solution for it?

Thank you very much in advance for you help.

Regards,

Jochen
