I don't understand why making the field a bit wider looks "stupid"...
Anyway, you can align the text in the field to the right if you change its Direction property (under Properties - Appearance), but then the arrow will appear to the left of it.
Alternatively, you can change the font size of the field so that the text fits in it better. You can use the Auto option to make sure that it always fits.
Thanks for the reply try67.
The reason I said it looks stupid is that I deal with people who spend all day looking at monitors looking for minuscule changes. Having a gap between the hours number and the ":" will drive them mad. I have already set the appropriate text size for the box as they found changing text "annoying" (as you can see, not an easy user group to deal with).
As far as aligning the text I don't seem to be able to "Align Right" the text in Properties - Appearance. I can align text in a text fillable field (where the user has to enter text), under Properties - Options, but this option does not appear for me when the data box is a drop down menu.
