Answer 1

The problem is explained pretty well at The Old New Thing:

The reason that WaitForSingleObject returns immediately is that Explorer is a single-instance program (well, limited-instance). When you open an Explorer window, the request is handed off to a running copy of Explorer, and the copy of Explorer you launched exits. That's why your WaitForSingleObject returns immediately.

He offers a couple solutions you could probably use (with some heavy use of PInvoke), like using something like this.

In the end it might just be easier for you to use some other type of file browser maybe from a C# library somewhere that you have more control over, rather than explorer.
