Always while i am running engine-matches :
------------------------------------------

-No surfing on the Net,no working with Word,not doing some Programming etc.

-Before to start each tournament under both GUI's the PC is restarted !

-For each GUI was setuped separate (different)folder of engine.exe

-No any program is insalled in the TaskBar !
