Several times today I had 500 SQ3.8.2 strategies loaded in the databank for retesting. Two of the times that I clicked the X to exit SQ4 froze with no error report. Task manager showed practically no CPU usage and the memory usage was not changing. I waited for about 5 minutes for SQ4 to close and eventually had to use the End Task in Task Manager.
I do not know what config file you want.
