Hi Jane,
So, yeah, it's a very "clarion" think to put colons at the end of a prompt.
However, this makes the transition to labels (which is better for screen readers) ugly. And also makes the use of floating, or fixed, labels ugly.
To make things consistent (and ultimately a lot more useful) removing the colons from prompts is desirable (and Nt14 does this for us.)
So, no, there's no easy way around that at the moment. Although there could be one if I was suitably convinced that the colon isn't just nostalgia for the DOS days.... So convince away...
