I've been running extensive backtests and have noticed that the applications slows down alot after 25 to 30 backtests in one session. Windows Task Manager shows the memory usage grow with each backtest that is run, but doesn't release that memory when it finishes.
This issue is now fixed in Version 1.2 of VectorVest 7 currently being rolled out to customers.
