Stops responding after returning to previous screen
I am developing a channel, using the roListScreen component. I find that when I go down one level, then use the back arrow to return to the previous screen, the system no longer responds to my button press when I attempt to go back down to the next screen again. I can continue to go up the stack, but not down. This happens on levels 1, 2, and 3. I can go down, and back up, but never down again unless I exit and come back in.
Can anyone offer insight on what I might be doing wrong here?
I am using the same code in each function, so I am wondering if there might be some sort of variable scope conflict happening. However, it is my understanding that the variables within a function are scoped to that function, so I don't see how that could be the problem.
Do I need to use unique names in each function?
They all currently look like this:
screen = CreateObject("roListScreen") port = CreateObject("roMessagePort") screen.SetMessagePort(port) . . .
If anyone can offer some guidance here, I'd appreciate it.
