Peter Tarkkonen 0 Report post Posted July 10, 2012 Had this same issue with TMG 7 and it shows up quite often. I have Project Explorer in my desktop. Lock happens when I filter (like last name is....) first And then sort the filtered view (like Birth Date) After that there is no way take control except thru system close TMG and start TMG again. Cant say this happens every time but 1-2 times out of 5. Peter Share this post Link to post Share on other sites
