How to stop LoveCode running in Edit mode

[Keith Clarke]

Hi folks,
Returning to LiveCode after some months away and am wondering why, in 8.1 (in Mac & Windows IDE environments) scripts on buttons, etc are still firing when I switch to (or open a simple stack in) ‘Edit/Pointer’ mode.

IIRC,  code only used to run whilst in ‘Run/Browse’ mode. This is making development & debugging hard work - have I missed a new setting that I need to disable?
Best,
Keith..
