OK. I figured out.

The problem occurs because I SHOULD HAVE provided a matching filter to NOT TO replace comma with dot (the default behavior it inherits from its parent ConvertDouble), but should instead filter out it. Morale is, Scan/Format/Filter should work together to assure the EditField is in a consistent state.

The second question, if you want to format a double to certain dicimal digits and with thousand separtor, you should:
1. SetLangue properly;
2. The format string should be something like this "%3!nl", which will format the number to 3 decimal points and with localized thousand separtors. Eg, in enUS, 12345.6 will be formatted to 12,345.600.

I had to go through the code to figure it. Maybe a example line can be added to the Format example to save somebody else some trouble in the future.

===============================
CORRECTION: the problem remains after a customized filter has been provided to take care of the comma separator. Now I am almost positive that it's a bug in the library.

I have attached a slightly revised test case. Just drag the text between the edits a few times, you WILL observe erratic behavior.
