Auto-refresh not working any more?!

Hi all!
I have this problem since I upgraded to dopus 10 (I think it's since then) and it's been driving me mad..
If a file is created in the directory I am in (from an outside source, e.g. another program), the lister isn't auto-refreshed. I have to press F5 every time !
I 'm almost certain this wasn't the case a year ago, but I could be wrong.. Anything I could do about it?

Please see Changes to folders are not always detected in the FAQs for suggestions on how to fix it, and information on how to debug what's happening if the suggestions don't help.

eeer sorry for the trouble, it was an afs network drive but I had mapped it to a drive letter and forgot all about it!!

thanks very much for your help!
