I have an app I have been working on for a few weeks, it has been working fine except that the Table Views don't seem to allow scrolling when there are more rows than are visible. I thought that perhaps it was due to some changes I had made to the Table code so I could set the row height, so I copied my version to a backup, removed the Module, and added the original back in. But now I am getting errors when running the app.
The first one is this:
Error occurred on line: 0 (table)

** Activity (schedule) Resume **
The strange thing, is that if I step thru the code using the debugger, it doesn't occur.
By the way, I tried putting my changed code back, but the error continues to occur.
What should I be looking at here?
