Apple Remote Desktop/PowerBook/Xserve problem

[3mors]

hi guys,
this is my problem:

i've installed remote desktop 10.1 on my powerbook G4 400 (OS X 10.2.5) and on my Xserve 1GHz dual (OS X 10.2.5 server).
On both of them i've used software update to update ARD to 10.2.

The ARD works fine, but when i'm connected from powerbook and i click on a folder on the xserve desktop, finder unexpectly quits and stays down.

If I use keyboard and monitor plugged on Xserve, all works fine, it happens only if i'm connected via ARD.

I've already tried to reinstall ARD admin on my powerbook, but not yet the client on Xserve.

I've already looked for a solution here in this forum and on Apple Support, but nothing.

Could u help me?
