Finder Window Quits on Browsing SMB Share

I have MacBook Pro with 10.4.10 and notice that often when I connect to a local windows server smb share via its \\ip.address\share it will happily authenticate and let me in but after browsing for a few folders of depth the finder window simply quits and leaves me having to make the share connection again.

any ideas on this - I have only done rudimentary searching and getting poor leads so I thought I'd ask straight out.

I had problems with finder closing, but not uniquely with one programme. There is a bug in stuffit which affects finder, so if you have stuffit installed try this.

cheers.

I suggest removing all together.

good lead, thank you for that unfortunately I don't use stuffit and am trying to get my head around when and why the browse quits.

i suspect it is smb/samba related and perhaps something to do with the authentication at the windows end - permisisions or something because they are set to be quite permissive but not by ad or anything.
