Crap im tired tonight =)

Please ignore the above posting... GetModuleHandle does *NOT* return a
unique value.  As a matter of fact, it is (currently) the same across
all Windows platforms.  400000 hex or 4194304 decimal.

Alot of coders I know hard code this value instead of calling the API
function which is slower.  Of course you should always use the API
because MicroSoft does not guarentee it will stay this way for future
versions.  If you need a unique number like the ThreadID you should
look elsewhere...
