Thanks everyone for your help. I am running Windows System 7. I retested both Tim’s version and my version IE 11 and the latest Chrome browser. They both work now in Chrome but not in IE 11 (not sure why it tested different this time). I will post what I find out while working with the Support team.
Tim, you are right about the “Always on Top” feature creating havoc. The interaction is something we converted from Lectora 6, then Lectora 11, and are now converting to Lectora 16. A number of elements where changed along the way to always be on top because either we were having issues with the buttons not displaying as expected or our client was.
I discovered what was happening here. When the invisible button in desktop view is smaller than in the other views (ex. 300×70 in desktop view and 444×80 in PhonePortrait view), the inv button is not clickable for the entire length of the button. This is an issue for ie 11. The button works fine in the latest Chrome and Firefox browsers as well as those already mentioned in this feed. I have not tested it yet in other versions of ie.
To fix this, we are redesigning the desktop screen to include bigger buttons.
