Hi Sai,
Got it, so you're on Orbeon Forms CE 2016.x, and I see what your form does
in the screenshots. I'm not aware of any issue of this nature, but there is
maybe something that we missed.
1. First, does it work if after making the selection with the keyboard, you
hit tab to switch to another control?
2. If not, could you share with me a subset of your form, that I could run
locally to reproduce the problem?
3. Finally, does it only happens with a certain browser, or does it also
happen with, say, Chrome?
‑Alex
