Touch screen stops responding, but only on rails collection_select dropdown

Leave a Comment

I have a collection_select in my rails view that displays a list of cars from the database. The web app is displayed (using Chrome) on a laptop that is connected to an Acer touch-screen monitor, which works well. I am having a problem where the cars collection_select field in my form will stop responding to the touch screen. I have done a ton of trouble-shooting, but I can't seem to isolate the issue.

  • The collection_select menu opens, but it will not scroll and you cannot select a car from the touch-screen monitor
  • The rest of the same browser page still responds to the touch screen
  • The collection_select works if you use the laptop's trackpad
  • Closing and re-opening the browser fixes the problem (until it randomly happens again)
  • Turning the touch-screen off and back on does not fix the problem

Does anyone have any ideas as to what might be causing this?

The app is using Rails 4.2, Bootstrap 3 and simple_form.
