..would pop up to tell you or ask you... would you like to turn off the current selection before doing...whatever? This process can not be completed with a current selection going.

Is it possible to write a script that would reside in your scripts or plug-ins folder or perhaps Gimps bin directory that would fire if you ever tried to start a process that required the selection to be NONE?

I don't how such a script would be possible. It would have to know the requirement of all scripts/plugins. IMHO if a script/plugin doesn't behave when there is a selection, it should be fixed.

On the other hand, it is possible to write a front-end script for a script/plugin that doesn't call the back-end it if there is a selection.

Thanks Ofnuts.

Good scripts (and plug-ins) will check for invalid or missing input and conditions.
That is where and how it needs to be handled.

Yes i agree, something for the developers to tackle i imagine.

Just take whatevert script is causing you problems & add a few lines of code to check if there is a selection...
