softice and WinXP

I used to use Numega SoftIce 4.0x on my Win95 without any problems. I've changed platform to WinXP and tried to use a newer version of SICE (4.3.0 Lite). After manual startup of SICE the net1.exe process spends 99% of CPU and system strongly slows down. All other common processes become slow and unstable (memory access violation). The symbol loader works very slow too. This way the whole system become frozen soon and just one thing works properly and fast - CTRL+D & HBOOT.

Has anybody ever solved similar problems like this ? I don't suppose that's a normal feature of SICE on WinXP platform.

I'm very sorry for this "evergreen" topic but I really don't have any idea to solve it.
