There was a big push in the LiveCode 8 dp cycle to try to get LiveCode closer to 6.7 performance levels with native encoding so you will probably find if you try 8 it will perform much better.

There could be some inefficient object iteration in there. I’ll take a look to see if it’s still there in 8.1. I recently sorted out some in the script find dialog and there’s a huge difference in speed so ideally we can make similar gains there.

That sounds odd. We’d definitely like to know if you are experiencing that in 8.1 RC 1.

I’d be keen to get a recipe for this also if you experience the same in 8.1 RC 1. I’ve had a verbal report of the keystroke thing in very long scripts on windows but still need to work out what’s going on there.
