I have the new Firefox called Nightly. I will check that now if I can find it. I have windows set at 150 for display my type but I have had that on always. I have Zoom Text but it is turned off and I only use it for bookkeeping. It has never interfered before. This just started after the last upgrade of Windows last week. I had to have my tech for two hours updated drivers, etc. and we have no idea what happened. ATP is the only one that is not perfect now.
I thought I had a virus but it turned out not to be. We were not sure what caused the problems. He did all the maintenance, updates on everything. Mystery for sure.
