*sigh* At least Office 2K should work. This problem is a M$ related problem and the workaround in 2.5.0 solved this problem for Office 2K but it seems they changed their WebDAV behaviour with Office XP again.

Well, I'll reject XP and I'll try with MSWord2000! I have installed your WebDavLogger, so I attach the log (I have tried to understand something but it's too difficult for me now, and I only have erased part of it!). Thank you! Michele
