Erwin, I have seen this before and it was always a memory leak in the external DLL we were using.

You can limit VFP memory usage using SYS(3050) and clear VFP cached buffers using SYS(1104). VFP itself is very stable in memory usage and has no known memory leaks.

Most windows app's will release a chunk of memory when you minimize them. For instance, minimize your browser and see the drop in memory usage. This in itself is not significant.
