I have a problem and would appreciate any suggestions.

Since upgrading to ZAP10, I cannot upload completed work units from Folding @ Home unless I exit ZAP10. The WUs download and process properly, but when they have completed and are ready to send to Stanford, my log is full of snippets suggesting that I could not connect to the Stanford server, e.g.:
Code:

I never had this problem in four years of folding on PCs with earlier versions of ZAP.

Additional information: Level of Trust in ZAP10 for my FAH client is "Super" and all inbound/outbound options in Application Control are checked. I can force the WUs to upload by closing ZAP10, then stopping and restarting FAH. Once the WUs have uploaded, I restart ZAP10. However, there are times when I will have to leave this PC unattended for extended periods, and I am concerned that I will eventually lose WUs.

Either I am missing a setting or there is a bug in ZAP10. Any suggestions would be appreciated.
