button hangup with modbus + and modbus ethernet protocol using lookout 6.0.2

[Haj]

I have lookout 6.0.2 HMI software connected to a network of modicon 984 compact PLC's using modbus + protocol, Control techniques Uni-Drives using modbus ethernet protocol, and Direct logic plc's using their ECOM protocol. I have all of the control objects built in the client process and all of the drivers are in the server process. I use a static symbolic link to connect all of the objects to the drivers in the server. My problem is every once in a while, one of the buttons will hang up and hold true until the button is pressed again.  I also noticed this only happens with objects that have a modbus + or modbus ethernet protocol. I've never experienced this problem with objects connected to direct logic plc's. I saw a posting related to this a while back but saw no solution to the problem.  Can anyone help?

I have never met this problem before. I tried for a while but failed to reproduce. I think it relates to how the button works. Lookout pushbutton sends out true value when you press it, not like the button of windows which takes effect when released. Could you try the CWButton, instead of pushbutton. Maybe it makes a difference.
