This happen when User is logged on and do their work (with Word or such).

- No change of IPrint Printerobject or IPrintmanagement are done

Seems, this is a Windows internal Problem but didn't find any usefull infos.

Have anyone an Idea whats going on here or some Hint's for Troubleshooting?

- Iprint Client 5.32
- Windows XP SP3 latest SP
- Novell Client 4.91 SP5
