The new mailbox I was forced to use has a serious problem, it flickers on and off each time I move the mouse to do any action.
It is upsetting to use..it flickers on and off at all times, each time I move the mouse to type, look at an email or ANYTHING the screen goes off and on and off and on. This is a serious problem and I will change to another mail provider unless I can have the previous settings restored.
