Presto() hangs

I can load stock Presto() examples and they will run. But if I were to connect via Thonny and run via REPL the command Presto() the whole thing will hang. If I were to cold boot the device that’s fine again. Bottom line: Presto() cannot be run more than once.

This is a problem during dev. The only way is to cold boot Presto every time I make a code change. Is there a better way?

Ok this fixes things: stumbled on this page suggesting Thonny connect using the Pi Pico interpreter; was using CircuitPython. Getting Started with Pimoroni Presto
