Hi there I hope you can help my brain is completely frazzled now

i bought the white label 7th hour, put 2nd disc in... installed saved to c:\oldgames\id\t7g

i put 1st disc in run it from oldgamess\id\t7g and it works fine. i can do everything but the mouse is "repeating" itself with every movement so eventually my whole window is full of skeleton hands!!

please help also how come it has managed to run in my windows xp laptop?

many thanks in advance xx
