1) There are ways to do this. They start off looking complicated, but you have to remember that asking the program to sleep _actually_ _works_: If you do that in the main program, the main program sleeps so that you can’t click, etc.? Instead, you have to hive your turnout activity into a little separate item (called a “thread”) which can run and sleep independently.



2) How are you running your scripts?? When I run something (i.e. while debugging) from a Script Entry window, the syntax error and runtime error messages show up nicely on JMRI System console window. Perhaps you’re running them a different way or there’s something else wrong?

Another clue that something is wrong is not seeing “turnouts” and “sensors” predefined.? They _definitely_ should be.

The only things that can be operated are the resize buttons on the window and the positioning. So I can't throw the turnout to let the test program complete (the log line appears every 0.2 seconds, so it sort of seems to work). I would have thought that the time.sleep(200/1000.0) would allow me to do things instead of the whole interface being locked up? (BTW: specifically not looking for different ways to do this; I know I should add a listener and make that react, and I will end up doing that anyway - I am trying to understand why the simple thing I'd like to do cannot work)

> 2) When I make one of my frequent coding errors, the result is the same as described above - interface locked up except for the sizing/positioning of windows). I get no error logged. Nothing on standard output or standard error,? and nothing in the console. Zilch. This leaves me having to guess where I could have gone wrong, instead of being able to look at a stack dump. For instance: I thought in my optimism that the variables 'turnouts' and 'sensors' where predefined when importing jmri, so I was happily using them. That caused the lock-up with no message at all. Finding the cause of that took me several frustrating days. I hope to turn this back into a hobby!
