I wonder if there are particular factors which trigger this. I’m working on a page of about 300 lines and am not having any problems at all. Strangely, I was having problems before the last update.
I do close Wappler (full quit option) from time to time if I notice things are not behaving - eg earlier I applied the formatter to a value and it wouldn’t update. At this point, I restarted and all was well again. Perhaps this helps, but I haven’t been having the editor freezing problem since the last update.
