Select from data list

We recently upgraded to Lawson 10. Somehow in the process, I lost the ability to just enter the first letter
of a field, hit my down arrow and have the next item in the selection populate. For example, when entering
a new asset, we have 40 locations. I could enter a P hit my down arrow once and Perry would populate.
I have not been able to find a setting to change this. If I right click on a field it says - Select from data list Enter
This is minor, but annoying.
