poclbm stops with multiple users in WinXP

[nosro]

I have reproduced the following problem several times. I am running poclbm and phoenix through guiminer on Windows XP. The configuration does not appear to matter. I have a Radeon 6850 and have tried Catalyst 11.4, 11.5, 11.6, and 11.7.

I have two user accounts on a machine ("user1" and "user2"). the miner is set up to run under "user1". With "user1" still running, if the machine switched users and "user2" logs in, the miner (poclbm or phoenix) freezes. Task Manager also shows poclbm or phoenix at 100% CPU utilization.

Anyone else see this or find a work around?

I have a satisfactory workaround for machines that are predominately idle: use BitcoinMinerSaver ( http://bitcointalk.org/?topic=8385.0 )

Details:
1) Set up BitcoinMinerSaver on all user accounts.
2) Install TweakUI 2.1. Under "Logon", there is an option to change the default screen saver for the logon screen. Use this option - it will then copy all screen saver options (which will be the Bitcoin miner) of the current user as the logon screen saver.
3) Reboot

Note that step "2)" is required because if users simply "switch user" instead of going idle (and letting that user's screen saver take over), then the default screen saver takes over rather than the user's screen saver. Step "2)" changes the default screen saver so that no matter which screen saver activates (User1's, User2's, or the Logon screen default screen saver), the miner runs.

Main drawbacks:
A) The BitcoinMinerSaver only works with one device.
B) Only works while idle.
