Why not simply instantiate a single instance and use that where necessary instead of completely reworking the class? > (In fact I am not sure, what happens when deriving siblings of TEpikTimer, as I am astonished that doing things like "class function SystemSleep(Milliseconds: Integer):integer; Virtual;" is even possible. Yes, virtual class methods are a big advantage of Object Pascal compared to e.g. C++. You don't believe how much I miss that feature when working with C++ at work. :/ > I fail to understand how a virtual class function is supposed to work, as I understand that without an instance there is no virtual message table.) The VMT is not per instance, but per type, so there is no difference there regarding virtual instance and class methods. Regards, Sven
