Well, if you don't want to stop your program(s) then I give you answer to your original question: yes, minimizing Windows application under Wine (or even switching to another desktop without actually minimizing it) will reduce CPU usage in *some* cases. It depends on your application. For example, Metrader 4: when it is online and updating almost every second information on my screen it will obviously use CPU but if I go to another desktop, CPU usage will go down a bit. Do you have a problem with particular application?
