Tabs not working in web editor

I created a 500 line sketch in the web editor which compiles and runs well.

I split the code into tabs in the web editor and couldn't get it to compile without errors. I spent hours searching for solutions but gave up and used the desktop (Windows) IDE instead.

The desktop IDE compiled and worked well with the sketch split over tabs.

I then imported the sketch into the web editor and it compiled and ran well.

Seems to be a problem in compiling sketches from tabs created in the web editor.

Your post was MOVED to its current location as it is more suitable.

I have no experience with the web editor, but can you elaborate on the errors? Maybe with the exact error messages that you got. And can you provide your tabbed sketch that failed (or a representative example)?
