Hi Peter

I have found that the sudden drop in memory usage only happens if the vfp app goes from a non-minimized state to a minimized state. VFP does not even fire its internal memory free-up routine if the app is not visible! In other words I tried

With _SCREEN

.visible=.F.
.WindowState=2
.WindowState=1
.Visible=.T.

EndWith

but vfp did nothing iro memory since it apparently realizes that it is not visible so therefore does not need to do the windowstate changes and therefore no memory clean up. Otherwise the above would be great LOL.
