Apologies if this has already been covered, but everytime I search, the results page doesn't load.

For some reason when I visit particular websites my cursor completely disappears but if I hover over a link the link still changes colour/underlines etc and I can see click, but the cursor isn't visible.

Has this happened to anyone else?

I can't work out why it is happening as there seems to be no trend - just very randomly on random websites.
