Hello Stephen,
Thanks for Joe's explanation and I'd like to provide more information,
I think the following discussion thread may clarify why the program uses so
many memory, and in addition why it can be reduced by minimize then restore.
Sorry the discussion maybe a bit too technical.

| Program startup involves creating lots of objects that are used briefly,
| then set loose. What you're seeing is that those objects have not yet
| been garbage-collected. .NET doesn't free unused memory immediately;
| you have to wait until the garbage collector runs. That way it can free
| lots of objects at once and run more efficiently. It makes your .NET
| app look like a memory hog, but really, it will automatically compact
| the heap and then give the unused memory back whenever another app needs
| it. So, short answer: don't worry about it.
