ShellExecute() is an API to start another process. Of course you don't
call that one. But I'm sure you're using some other shell API which
loads the shell dll with the extensions.
(hint: those api's usually start with SH* or Path*).
Just step through your app until the dll's are loaded (you should see
that in the debugger window). Then you'll know what API call is
responsible for this.

What do you think the setting "show overlays only in explorer" does?

In that case, you're not correctly loading the shell dll or you don't
correctly unload it after using it. I can assure you that the tsvn
shell extension has no memory leaks at all.

Ok, then *you* do :)
