Did you make any recent changes to CrossOver or your Mac?
If the issue persists, please provide a screenshot via

I made no changes whatsoever - it just started looping from one query to the next. After many process kills and re-boots - KVS just seem to keep searching (info line on the bottom shows result count in the 1000's) then gets a timeout error.
I am at the stage of trying to un-install and re-install to see if that helps. I can send a screenshot but I don't think that will provide any additional information - all types of searches fail after "looping" for 5+ minutes. (Note KVS is still working fine on my iMac - it's my MacBook that is failing.)
UPDATE - I un-installed KVS using the KVS un-install utility and then removed the "bottle" from Crossover then re-installed KVS - it is now working fine.
