Delete protection and Multisurface Undo

[sturgis]

First thought. Probably not this one, but will throw it out there. More likely is the 2nd option farther down.
On an off chance.. Are you working with transparent buttons with no icon set yet? Or buttons with no border or shadow or anything of that nature? If so, there is a really WEIRD method where the name of the button changes to "button id idnumber" but the name doesn't display on the button even if the property is set for the button to do so. Can you check the app browser to make sure there are no buttons like that in your list?

To get what I mean, click a button, get the properties. Make it transparent or non-bordered so that it blends into the stack. Click in the name field and delete whats there, then click on your stack again. The button poofs, there is no name showing, and you're looking at the stack inspector. Click where you KNOW your button is, and it should select and show the "button id 1012" in the name, yet no name showing on the button.

I have noticed really strange things like this happen when i'm on my laptop because it has a really big annoying pain in the tookus track pad placed in such a way that its pretty much impossible not to brush it once in a while and get weird clicks and behavior.

Even if this first option isn't it, seems like a bug to me.

The other thought is related. If you click in the box to change the name, move the mouse out of the way, start typing (including deleting stuff from the field) and you brush a touchpad just so, thereby removing focus from the field, "poof" the control is gone and the inspector changes to the stack.

I've actually considered turning tap-click off on my touch pad just to make this type of thing stop!
