Problem - CEdit displays entered character 4 times

I'm buiding a dialog-based App and use lots of the CEdit-Control to enter floating-point-numbers.

My problem now is that every single CEdit displays the entered character 4 (!) times in its field, for example:

I enter "123"

The CEdit says "111122223333"

I cannot think of anything unusual I have done to the CEdits, only the Number-Flag in the Properties-Editor is checked for all of them. But diabling this flag did nothing to solve my problem. Instead of 'a' I get "aaaa"...

Any clues what's going on here?

Bye!
