Hi together, i want to go through a Loop every 10 seconds. But depending the code inside the loop, the time differs. E. g.  Do    Select    Case @SEC = 0 or @SEC = 10 or @SEC = 20 or @SEC = 30 or @SEC = 40 or @SEC = 50       ... do something ...    end select  Until $bHotKeyPressed  How can i be sure that the loop will be done exactly on the 10'th of a second? Thanks for your help! Dizzy
