If you have multiple Telemetry pages (one of them being this LUA script) you cannot switch pages of the script easily anymore:
The Menu button does nothing and the Page button does change the page within the script and it changes the active Telemetry page (in my case to a Sensors view) – leaving the LUA script.
This makes switching pages tedieous and the best alternative is to use the script within the Tools page, because there no multiswitching happens.
