Type-ahead support in Timesheet Dialog Boxes

In "Enter Time Sheet" dialog, if you type first letter of project name while project box is highlighted, selection goes to first project with that letter.  However, all subsequent letters you type appear (for not clear reasons) in the "Hours" box.  So if I want to select "IT Maintenance", and type IT M into the dialog box, I get IT Development selected in the project box, and T M appearing in the Hours dialog box... (see attached image for example of this) :(

Anyhow - would be good if this, and other project selecting dialog boxes could be changed to support type-ahead of some sort.
