Nope. Haven't seen this. When you say "rerun", what steps are you taking?
Are you remembering to download the program again? Also remember that
unless you do a hard reset or there's a special soft reset function on your
board, not every bit of state will be reinitialized when a reset happens.
So if, for example, your program configures a peripheral in a certain way,
it may remain that way after the reset, even with a different program.

I know the EPI Jeeni is both popular and useful. There's no thread
debugging though, be warned.
