Hi Guys
I discovered the exact same problem - NI recognizes this as a bug and as usually there is no horizon for when it is fixed.. fortunately another bright mind on this very forum came up with a solution that works.. minimizing the window programmatically will not work, as it does not trigger the same chain of events in windows - look at the thread I posted earlier here:

I've now redone the library to run on LV8.6 as well, and made a very simple VI to empty the memory of the process with "VIname.exe" - it works like a charm - i flush the memory every 10 minutes, but a more elegant solution would be to check the current memory consumption of the program and then set a trigger level - but I have not worked out a solution for this..yet.
