Perhaps, there is a bug about multi-touch

Dear All,

Test environment :
Software : Windows 7 32/64-bits, Multi-Dispaly supported and with the default multi-tocuh driver of the windows 7.
Hardware: Multi-touch screen.

It looks like a bug in multi-touch system.
The multi-touch doesn’t works on the secondary desktop if we don’t connect the monitor to the secondary VGA port, We can enable the secondary monitor by conrol pannel.
Actually, There is a bug in multi-dispaly in Windows 7 of the early versions, It doesn’t enable the secondary dispaly by conrol pannel if we can’t connect the monitor to the secondary port.
I find it about two years ago, At that time, I had to find a solution to bypass this problem, I ran into another problem today, Maybe, I’ll patch the default driver or the related API.
Could you give me some suggestion? Thank you!

Best regards,
Allen

If it works on x64… instead of the touch bug, are we now up to a patchguard bug?
