Closed Captions in Cp prevents buttons from clicking

Question

I recently added closed captioning to the existing audio in my lesson. The lesson worked fine before I added closed captioning. Also, it works fine in preview mode, and I can turn CC on and off without any problems. However, when I publish the lesson, it plays fine -- but buttons on the screen don't work. The symptoms are strange: on the first slide, the button's active area appears to be offset down by about 30 pixels, so I can still click the button. But on the next slide, the button does not appear to be active at all. This appears to be some type of bug. At first I used a mobile skin because the buttons were larger. Thinking it to be a bug with the skin, I changed it to the default skin and it still happens. Works in HTML5 preview, but not when published. One other strange symptom, if I leave the slide alone for a few minutes, I can then click the button. But I can't click it no matter what I try if I don't leave it alone.

Thank you Lilibiri for replying. I just saw your email when at the same time I discovered the source of the problem. It turns out that I had also selected borders to be turned on in my skin when I added closed captioning, and that led to offsetting the active areas of the buttons. All buttons were affected. When I turned off Show Borders in the skin, the lesson began to work correctly. I don't know if this bug was fixed in future versions, but I hope so.

Hmm...have a vague memory that I already did see this question somewhere? Is that the case?

You are not on the most recent version which is 11.5.5.553, which is the only supported version under CP2019 for Windows.

It could be linked with having a very large resolution, and turning on Scalable HTML. Did you try if you can reproduce the issue if you turn off Scalable HTML?
