when I said it occurs once or twice a week - - i meant per machine, we have some that it occurs 2 or 3 times a day - but that by far is the minority ....
as i stated before this just started happening within the last 4 - 6 weeks...it started very very random and on most machines it still is, however there are 2 that it seems to occur more on ....
I did try to reinstall it on one of the servers last night and now will wait and see if that fixes the problem
