Yeah totally wrong...  A negative handle???  Think about it...

Yep, well here's the rub... I took an older system I have laying about and set
it up witn win98 and ran my project... it doesn't do it there!  According to
the SDK that's because 9x versions don't assign handles above 65,535 ... i.e.
only the low word of the 32 bit handle is used, which won't cause a range
check error.

Not if...
A) nobody is using direct winapi calls on nt/2k/xp or
B) nobody bothered to report it.

One has to ask how many people tried this, ran into trouble and just moved on
to some other compiler without ever bothering to report it...

Matt is right... Longint is absolutely the wrong declaration for a window
