Hello,

I'm usually just lurking but here's my contribution for what it's worth.

-- Software ID: win32lib
-- Version:     0.55.1 19/Dec/2000

Line 1620 contains an error which results in SIZEOF_MSG being two bytes 
too few. Consequently acquire_mem(0, SIZEOF_MSG) grabs less memory than 
required and calls to GetMessage write past the end of the allocated 
memory with unpredictable results. If this has been fixed in a later 
version of the library then "good on yer" ;)

-- Type MSG
    msgHWnd      = allot( Long ),
    msgMessage   = allot( Integer ), *** Should be allot( UInt )***
    msgWParam    = allot( Long ),
    msgLParam    = allot( Long ),
    msgTime      = allot( DWord ),
    msgPtX       = allot( Long ),
    msgPtY       = allot( Long ),
    SIZEOF_MSG   = allotted_size(),

HTH.
