Is it my Computer or the BCST Site?

I'm reading "No Half Measures" and am almost finished. It is a very good story.

I notice that if I pause reading for more than a minute or two, the page freezes. It could be my Computer. It is aging and I'm getting ready to get another one. It runs on Win 10, and we all know that I am most certainly no Geek.

I am wondering if the issue has something to do with where the story is stored?

Any ideas?
