Just to add a little more to this. I suspect a number of readers already
realized a really simple solution to this specific case is to simply test
the read/write state in the On timer form event and NOT update if it's read
write.

This turns out to be a better solution in my case because it's a single
place to test it vs. multiple points in the code otherwise. Easier to read
and understand.
However, it's also totally effective to just change toggle the Set timer
event on and off as Arnaud suggested, and in a different case could be
better.

Once more this turned out to be more of a question of how to look at the
problem.
