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)?

What is happening in your scripts? I suspect you might have some heavy CPU processing going on.

If you invoke wait(0), you can force the GUI to refresh. Try it.

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.

I will check.

No it is not working. it is not a blocking due to to heavy calculations, it is a Zorro internal drawing topic.
As I said,Zorro is working and trading, but only a restart of the gui helps. Thats why I casked for a dedicated Zorro command to restart just the graphic interface without the interdependencies of the gui restart.
