GPU not found when Boinc runs as daemon

(moderation:
I ran BOINC under an ADMIN account and the GPU was located and used. 3 WU's were finished OK. It looked like the WU's that ran while another user was logged on to the PC crashed. Only the WU's that ran on the GPU were affected. After uninstalling BOINC and reinstalling it to run as a daemon the GPU is not found?? Can anyone help?

Both of these are known issues and have been discussed extensively in other threads:
1) GPU apps don't like user switches. If you must change users, you should shut down the BOINC core client and science apps first. CPU apps are not affected.
2) Due to the new driver sandboxing in Windows Vista and Windows 7 (all flavors), the BOINC core client is unable to detect the GPU when it is running as a daemon. If you want to crunch on your GPU, you must run BOINC from a user account.

6.12.15 doesn't have the 'fast user switch -> GPU suspend' fix included. Wait for 6.12.16, which should have it.
