Occasional odd loading behavior

In creating a new clock app, I find that occasionally loading it onto Bangle 2 fails and the IDE presents a lot of the code in many lines, then takes it away and presents:

echo(1)
undefined

Reloading almost always works, the above odd behavior occurring maybe 1 in 5 attempts, and only after I've changed a small detail (like color) in the code. Suggestions as to cause? Possibly a bug in the IDE?

I'm not a programmer/coder but am on my own for this glitch, which doesn't seem to occur on loading other code the same way.

How do you load the code with the IDE? Is the upload button set to RAM or to a storage file?

"Send to Espruino."

There is some text right under the icon. What does it say?

It says Flash. I assume it should be RAM, having now checked the Development page. Sorry for the very basic question.

The problem continues but less often. Now the occasional error is only that a term is undefined, which it isn't. (Same term every time.) After that notification, reloading from RAM always works.

If I'm not doing something else wrong, is there possibly a bug in the IDE?

Ok, well I think one issue is you'd overwritten your bootloader with your app by writing to flash. Check out https://www.espruino.com/Bangle.js+Devel­opment#using-the-right-hand-side-of-the-­ide

You need to reinstall the bootloader then either write to RAM or Storage. Once you've done that, it may fix a lot of things :)

I feel much better, even if the watch may not :-) (The IDE still presents errors that aren't, occasionally.) Is a complete reset of all installations necessary?

I'm not sure I understand? Just reinstall the bootloader if you overwrite it with the Web IDE. You don't have to reinstall anything else

Thanks. I did reinstall the bootloader after you suggested that and before writing the above.
