A very simple reproducible instance of the wandering red dot but only in LC 9

(tested in DP2, DP4 and DP8) is pasting.

make a button with

on mouseUp

   put x into y

   put y into v

end mouseUp

compile script

place the red dot at "end mouseUp"

now copy the body of the handler (2 lines)

and paste them after the existing 2 lines

watch red dot wander, repeat etc.

This kind of pasting does not make the red dot wander in 8.1.0 nor 8.1.5

@Bob Hall

I installed your patch to my version of LC9 DP8

https://github.com/livecode/livecode-ide/compare/develop...bhall2001:bugfix-20140

In preliminary testing it works fine and is a lot faster for longer scripts. Gutter is in perfect sync to the field.

As a test case for scrolling I used "revIDELibrary" which has 12000 lines.


Additionally it fixes the wandering red dot breakpoint problem I described above (bug 20145)

Thank you very much for the patch

Kind regards
Bernd
