Re: [python-win32] problem accessing OPC clients from thread

Hello, I've gotten my OPC client to work well under a multi threaded wxApp. Now I am trying to create a single threaded App because, from what I've learned from users on this list, it is a simpler and cleaner way to do ththings. I've setup a test script that allows me to catch DataChange
