Pages go "blank" after updating.

I attach a file, .ods, every time I open the Internet, it is an Expenditure File because of online banking.

Suddenly, when I updated, the file goes black [blank] whenever it click on the item in my Taskbar?

It affects the Internet Page I am reading, it too goes “black”; I have got to go to Expenditure File, open that, then clear that out of the way [the taskbar] before I can see the webpage?

It is doing wrong, what settings should I be looking at to stop this?
