[ubuntu] Windows XP shared folder issue

Hi, I am at U14.04 and VB 4.3.10.

I have installed windows XP and I do know that I am running with very low RAM (4 GB total) but I don't think that THIS is the root of my issue here.

I have another Linux partition with a folder into this called 'Customers' that I shared and added to shared folders at my WXP VM. It doesn't keep in the list and I believe that it happens because I don't have the checkbox 'make permanent' to check it. How can I fix it?

Thanks!
