I have a similar problem, and as I am not a computer expert makes things worse / difficult as I depend on my website to make a living!
I tried to add a new product, but when i tried to select a product category it would not allow me to do it, with my screen going grey and a rolling image ,like a horizontal barbers pole’, intimating something happening which it did not. I logged out and relogged in tried again, still the same problem. Every time I tiped something the screen went a shade of grey. When I clicked on the help button I got the ‘barbers pole’ again.
Working on the home page sheet was fine but this is a problem I need to resolve quick. Any suggestions? If necessary I will start from scratch but not my ideal option.
