Dropdown Autofill Error When Caps ON

Hello Experts,

I have a rather strange incident occuring in my Access dropdown controls, that i'll try to explain.

Lets say i have a dropdown with the following values:

Apples
Appricots
Oranges


Normally, when caps lock is off and i start typing app each letter is overwriten until the user finds a match, as it is expected.

However, when caps is on and i start typing APP the first p is converted to lower-case and the autocorect icon pops up, however the second i type in the 3rd letter it contines caps, and the dropdown stops overwritting, so i end up with ApPLESples

How come it stops replacing? Is there an easy fix to this, or should i have on every dropdown's gotFocus turn-off caps.  I'm not even sure if this is possible?  

Any thoughts?
