Hi Justin,

could you have a look at the patch I send in for *MOUSEHOVER* stuff.
Apparently Win98SE returns 0 without setting last error for the
Could you incorporate this into your patch?

Mine is a bit 'overcomplete' as ERROR_CALL_NOT_IMPLEMENTED will probably
never be returned (only for SystemParametersInfoA itself).

Shouldn't we also always do a SetLastError(0xdeadbeef) before every call
to SystemParametersInfoA?
