Laptop does not come back from standby

[stanger]

I am using ASIO4all v2.7 with Traktor 3 on a Dell Latitude D620 laptop on WinXP Pro SP2 with an Edirol UA-1EX as my main out and my internal soundcard as a monitor. Traktor works flawlessly with ASIO4all, but my computer does not come back from standby. It activates normally, goes to sleep fine, I press the power button to wake it up, the power light comes on, my wifi light comes on, the harddrive spins up and does a little activity and nothing more happens. The screen does not activate and the system is non-responsive. Standby key, ctl-atl-del and windows key, up key, enter, enter (to try and shut it down) do nothing. I end up having to do a hard reboot by holding the power button down. I uninstalled ASIO4all and the problem went away. Reinstalled and it came back.

I love ASIO4all and the ability to standby my laptop to travel and still have it ready to rock quickly, so any help in reconciling these two functions would be greatly appreciated.

thanks.
