I am running 10 Zorros parallel on a trading pc. Very often I have the effect that some Zorro Gui windows are blind (White, broken), but Zorro is running correctly. Is there a dedicated command to repaint the window (also between the TF action for a new bar)?
Actually CPU and RAM are not overloaded, it is just a display topic and it is a recurring one. I will try your proposal. It could be also a Windows issue.
