I have a PDA application that allows the user to enter answers to a series of questions, and save the data to a text file.
After a while it stops responding, and I don't know why despite many hours of searching - the code, forums, knowlege articles, documentation. If the solution is there, I have missed it (but I learned other useful stuff on the way) Can anyone advise what the problem is?
Attached is a much simplified version. 20 pages with navigation buttons, each page has a field called text (where the answer would be entered) and a comment field (for further observations). Some initial text is populated in each when the application first runs.
Navigating through through the 20 fields and editing them (adding text), then saving the file, multiple times, eventually leads to a lack of response from the control buttons. They change when tapped, but the application doesn't respond. I'm afraid it can take quite a few cycles to produce the error. Once this point is reached however, with the focus in one of the data entry fields key strokes on the PDA virtual keypad continue to update the field, so the PDA itself hasn't stopped responding.
If this is automated (just click the run button) the application doesn't seem to fall over. Letting it run like this for a while and then reverting to manual does seem to speed up the process of getting to the failure though.
I'm using LabVIEW 8.5, PDA module 8.5, and I have WinXP on the development PC and PPC 2003 on the PDA.
I'm guessing either there is some form of memory leak, or I'm hitting a limit in the amount of data that I can handle somewhere.

Hang on, it's going to help if I include the run time menu (so you can save - the other menu features don't do anything) and tell you that you are supposed to run "PDA forum example.vi"
