I've noticed that when you have a textbox, let's say it's bound to a field in a cursor, the field can be empty and if you click on the textbox since it's empty it positions the cursor automatically at the beginning of the textbox, BUT I can hightlight with the mouse a portion of the textbox let's say in the middle of the textbox and start typing there which doesn't make sense for me. It's causing problems with my users b/c some will click on the textbox and without noticing they had moved the mouse a little bit thus highlighting a part of the textbox and before they know it they're typing in the middle of the textbox rather than at the beginning.

How do you guys handle this? Any comments?
