GPU tracker stuck at 100%?

I was using 5 computers with same specs with a GTX470. This morning when I checked them I noticed that all of them were stuck at 100%. Is there any explanation for this behavior? The last few lines from the log file:

[00:38:38] + Attempting to send results [December 20 00:38:38 UTC]
[00:38:38] Gpu type=3 species=30.
[00:38:43] + Results successfully sent

[00:38:43] + Starting local stats count at 1
[00:38:47] + -oneunit flag given and have now finished a unit. Exiting.
Folding@Home Client Shutdown.

After this there is nothing for 6 hours until I stop and than started the client.

What version of the Tracker are you using? Also please when this happens I would ask you to look at Task Manager to see if there are duplicate processes. If there are more core 15s open than you have gpus for then that is a bug that can happen. If this is the is the case then they system is folding fine its just not tracking the correct core.

It was 3.39 yesterday. Using 3.40 that came out today now.

Should I worry about User Access Control settings or run as administrator?

You need to use "Run as Administrator"

You are right disabled the UAC and it looks OK now. Thanks!
