I have an MFC application that upon startup uses about 20MB of memory
according to task manager. I noticed that if I minimize the app, memory goes
down to about 1MB to 2MB and never returns to 20MB even if I restore the
app.

I noticed every other app does this as well. VStudio from 50MB to about 3MB,
Outlook from 57MB to 5MB, etc.

Seems like some garbage collection is getting called or something?

How can I trigger this behavior without programatically minimizing my app
which looks ugly on the screen.
