How to stop LoveCode running in Edit mode

Thanks Richard & Alan for the response. It looks like a plugin is responsible for this strange behaviour...

Richard - great and comprehensive background information on some of the things going on in LiveCode 'under the hood'. My primary use of the IDE is to create utilities and prototypes - so I consider myself very much an IDE ‘driver’ rather than any kind of ‘engineer’. Thanks for the first-level checks. I created a new stack on 8.1.1 with just a button and a right-click didn’t reveal a menu, despite put the mode of this stack = 1 and put the cantmodify of this stack = false.

Alan - thanks for the tip regarding plugins & BvG Docu. To continue the above car analogy, I don’t venture under the hood but I have a whole raft of plugins that I’ve collected over the years (with little thought to housekeeping), including BvG Docu 2. I’m sure many of these delve into LiveCode’s inner workings. I moved BvG Docu 2 out of my Plugins folder but the behaviour persisted. So, I emptied the Plugins folder and LiveCode 8.1.1 seems to be behaving as I expect to see. :-)

Am I correct to assume that a clean LiveCode installation would have the Plugins folder empty? I ask as despite clearing this out, I still see a couple of third-party plugins listed despite the Plugin folder being empty - e.g. Data Grid Helper. Have I further housekeeping to undertake to clear the decks of any obsolete code?
Best,
Keith..

Instead, regardless of what the global "tool" property is set to, when the "cantSelect" of a control is true the object will always behave as though the "tool" global property is set to "browse tool".

The "pointer tool" will only affect stacks open as toplevel, which allows us to have palettes, dialogs, and even other modeless auxiliary windows which are unaffected by the current tool mode.
