Drop Down Lists disappear

[WhiteStuff]

Hi, I've been having this issue for a ling time and thought that maybe today is the day to troubleshoot it and fix it!. I love drop downs for filling out forms. But a while back my drops disappear quickly and I have to click escape to get them to come back. Then when  stepping down a list, it will disappear again. Very slow and frustrating? I keep thinking that an update will fix it but it hasn't through 3-4 upgrades. Maybe a preference is corrupted? Where would I find the correct one to delete? Thaks for any/all suggestions

Are there any triggers on the field?
