Windows stations, desktops, and Winforms

P: n/a
From a parent process, I created a custom windows station and desktop.
I then CreateProcess using that
new station/desktop. There are no problems launching a plain windows
app with this station/desktop.
(I tried some simple apps and notepad.exe) However a Winforms app
fails.
If I use the default station (Winsta0) but a custom desktop, the
Winforms app does work.
I would prefer using a custom windows station, but I'm close to
punting :(

Winforms fails this way...

The ExternalException's HRESULT is E_FAIL (which doesn't tell us
squat)

Has anyone seen this problem?
