Issue with Photo Gallery

Hi,
how are you demispatti ? Hope you are well.

I see there are an issue on my Gallery page created with Photo Gallery plugin

My Gallery Page:
https://www.peopleinside.it/gallery/

For reproduce the issue:
– click on the second album (middle album)
the gallery will be loaded

– click on a picure
a popup frame will be showed with the image, no issue for now as you can see scrollbar are showed correctly.

– close the popup frame window
now the browser bar will be showed over nicescroll bar

How I can fix that? Should report the issue to the Photo Gallery or can be fixed from here?

Thank you so much!

Wish to you a very great end of the week.

Marco
