[New Beta is resource hog?]

Update - installed the production version and have much less CPU usage than with the above beta.  Several cores are close to 0% utilization and overall CPU usage is under 10% generally.  Happy camper here.

[New Beta is resource hog?]

I installed version 1.1.2244.203 x64 recently and now have what appears to be a resource issue.  I have an 8 core processor with 6GB RAM and Windows 7.  When the program is open, I can barely use the keyboard....long pauses between seeing keys pressed.  And when I try to use the keyboard my system fans speed up.  Looking at resources in task manager shows all eight cores bouncing from 20% to 60% which may be normal.

Please let me know how to downgrade so this does not happen.    Or, if this is known, when another version with a fix might be coming.

Thank you,

Ed
