Certainly those are things to consider. The problem with allowing currency symbols to be entered is making sure that it's in the correct position to represent a valid value. Also, some currency formats might require multiple characters, so you'd have to allow them to enter one without any guarantee that they'd enter the rest. I think probably allowing a valid currency value to be pasted in but then stripping off the currency formatting would be a good idea, but not allowing currency values to be typed in. I think the same for group separators would be the way to go. I'll also correct the fact that different decimal separators are not supported. Thanks for that.

I've recoded things a bit in an effort to get the NullableValue, Value and Text properties to play together a bit better. I should have that part sorted by tomorrow, my time, so I'll look at the issues you raised after that.
