Disabling windows

BlitzPlus Forums/BlitzPlus Beginners Area/Disabling windows

Having written almost no B+ apps, I've run into a problem with a simple about box.

Is there any way to disable a window when another opens?

When I click my help.about, I've got my about window opening, which is great. However, I can simply click back to the main window and do stuff.

I realise, I can simply disable everything in the main window manually, but I'm trying more for a reaction as in the BlitzPlus IDE itself - where the main B+ IDE is disabled when the ABOUT window is open. You can't even select it.

I thought making the ABOUT window a member of the main window group would do it (as a parent/child relation) but it doesn't. There's something really obvious I'm missing but can't track it down in help.

Can anyone tell me? :)
