Arrow navigation doesn't work II

Hi! I am facing the same issue as a few of others, as per this thread (marked as resolved, but I don’t think there is an actual solution there…): https://ww.wp.xz.cn/support/topic/arrow-navigation-does-not-work?replies=4

My laptop has a touch screen, however I normally use a mouse… So I can’t navigate the slider with arrows or pagination icons, when using a mouse, which is quite inconvenient & counter-intuitive. An extension of this problem is when I connect an external monitor to my laptop – in this case I don’t effectively have a touch screen any more, but still can’t use a mouse… –> can’t navigate the slider at all.

Here is my website:

Otherwise, I have been using this plugin for about a year, and I really love it! Thanks a lot for a great plug-in.

Kind regards,
Sasha
