MT4 Crashing when saving set file

 
Every time I try to save a set file in the Strategy Tester screen MT4 it is crashing. It happens when I click on the save-button and the Save As-screen opens it's crashing after a couple of seconds. I have reinstalled version 432 and installed version 438 but it's happening in both versions. Anyone the same experience or is it a local problem on my pc? ( I don't know if it has any impact but I have installed today the upgrade of JAVA to version 6 Update 35)
 
Don't install in c:\program files* on Vista/win7
 
Issue solved. It appered to be a permissions issue in Vista. When I open MT4 as administrator I don't have any problems.
