Difficulty choosing top line in a drop-down menu list

I am having great difficulty clicking with a mouse on the top option of a drop-down menu. Its not always possible to switch to manipulating the list with my keyboard either. I can move the mouse to get the top option highlighted in blue but clicking fails to change to that value.

Gender: correcting unknown to male
Place: choosing the top version of various near matches when entering
Person Search Advanced: for each column

WebHints is the worst problem because I cannot access them despite having lightbulbs. I cannot even get that top line to outline in light grey like the Problem Alerts and FamilySearch choices do. It shows me how many there are and pending. TreeShare is connected to my Ancestry Tree and functions properly. So I dont think its an ancestry connection issue.

Any ideas?
