I go through my email to delete all unwanted ones. Click, and it highlights, click on next one and it will NOT highlight until I refresh. Repeat for each item, always needs refresh. OPEN and read one email, attempt to DELETE and nothing will happen until I refresh after each request to delete or even move to NEXT email......tired of refreshing hundreds of times each day simply to read and delete my spam and emails. This started about two months ago and I am out of so-called "fixes". PC Booster cannot solve this after spending hours and hours with them.
