How about some hyphens?

I don't know why this wasn't done from the start. I go cross eyed looking at all the numbers.

Hyphens, no periods please - my vote!

Why not do it the way Excel or other spreadsheets do it: the database holds an unformatted number, but we are given several formatting options for the way the number displays.

My understanding is that they are redesigning VPanel. Chances are they won't put much effort into changing a system that won't be used for much longer.

EXACTLY

This is the best answer. Especially if, like Excel, data input can be accepted in the formats possible for data output (And display as the format preferred, once entered.)
