KEYBOARD action causes screen keyboard to disappear then reappear.
Thanks for such an amazing tool!
I just used a 9 button scene and KEYBOARD action to create a DPAD and give myself the &^%$#@!!! arrow keys (and, eventually, the Delete key) missing from most keyboards.
Good news: It works!
Bad news:
The keyboard disappears, then reappears after a beat.
It's kind of jarring to use, as-is.
Setting the "don't restore keyboard" flag is an ok workaround, but if it's possible to choose not to hide the keyboard that would be useful.
