Small issue with custom formatting. Most of the ones I've tried work, but have a requirement to present a number in K dollars (ie divided by 1000). Easy way in excel is to use a custom format like this:
$ #,##0.000," K";0
which would display 60,000 as 60.000 K.
However in radSpreadsheet it shows the value as 60,000.000 K, getting part of the customization right, but not the movement of the decimal.
