Thanks.  This was reported earlier. It will probably only happen on 
long running programs. Anyhow, I've fixed the issue now for the next 
release.

If you'd like to test it, in the eventLoop() routine, replace the lines ...

 w32Seed = xor_bits(floor(w32Seed), peek4u(msg+16))
 w32Seed = xor_bits(floor(w32Seed), peek4u(msg+20) * peek4u(msg+24))
 w32Seed += 1

with 

w32Seed = remainder((w32Seed * peek4u(msg+16)) 
                    + 1 + peek4u(msg+20) * peek4u(msg+24), 
                    #FFFFFFFF)
