I don't think that the color change has anything to do with "active module that I am making changes to".
I can change the HCUC, name, etc., and the color does NOT change.
There must be something else that the color change/"lifts up" means....
Try it for yourself....
click on the module when the pointer icon is an open hand. the module background changes color and it appears to "lift" off the "desktop" or window.
Then click on it again and the color will change back and it will "drop" back to the "desktop".
Then change the name of the module, change the HCUC, turn it on or off..... anything where the pointer icon is a pointing finger, and the module does NOT change color or "lift".
Could this be a "feature" that was thought of and didn't go anywhere?
hhmmmm.....
