Google Picasa and Windows 7 - Unable to save to disk - Disk error

Just ran into a small issue while trying to export JPEG files made from RAW files provuded by 25 megapixel Sony Alpha 900. Every time I've tried to save or export the JPEG, Picasa would say that there is a disk error or it's full. After trying a few things here and there the solution finally materialized - you need to run Picasa as an "Administrator".

To make this a permanent fix - right click on the Picasa icon, go to properties, go to Advanced and put a checkmark to always run the program as Administrator. Now you should have no problems exporting or saving files from Picasa!
