Perhaps, but the same code running from the runscript is still executing, just in other ways, window event or timer event for the instance that needs to run continuously. So based on that, it’s hard to agree with you. Like I said, I’ve given the project to support to look at it. Works fine in 8.1.1, later versions it doesn’t. Whatever the problem, it doesn’t matter to me, I just would like to figure out what the problem is.
