OS 10.5 - Finder problems - closes window.

Hi,

Im having some problems with finder on my macbook.

My mac is connected to a wireless server, this is displayed on my desktop as "public", it is a samba hd.

When i enter the public directory, and try to click on a folder, it closes the whole window. I dont even have to click just hover my mouse over the folder and it quits.

I know this is not an issue with the server, as i can access the directory on a windows pc.

Does anyone know the cause of this issue?

Is there any software that i can use to correct this?

Any help is much appreciated?

Thanks
