I figured out the problem and it seems to be yet another bug in Zorro.

I added the line

Code:
brokerCommand(SET_COMMENT, Algo);



to my script that was trading with MT4, that caused the Zorro to freeze up while downloading the price history and not show any server time any more. And in the log windows it was just printing dots .....

It also caused my other two running Zorros to not respond any more.

When I removed the above line from the script everything worked well like before!!!
