Bug using keyboard in confirmation dialog

[neub]

I am using CSS/BOY 3.2.16 and I have found a small bug with confirmation dialog and keyboard:

• I have used a Boolean Button with Confirmation Dialgog when Pushing
• This button is connected to a PV called $(user):CtrlRstCmd that when we write 1 inside it reset some part of our HW and go back to zero automatically.
• If I press the button a confirmation dialog is open
  • If I use the mouse to click Cancel, No or Yes everything is working well
  • If I use the keyboard to select: Cancel, No or Yes, the mouse stay in "pressed mode" (icon of finger in my PC) and when I click again the confirmation dialog re-appears.
  • This action can be done in loop until the mouse enter in another clickable widget.
