Agentry, disable Numeric field keypad in WindowsCE

Hi,

we use Agentry Server 6.1.4.179 and the WIndowsCE client version Agentry_6.1.4.54024_ClientWinCE.

The small numeric keypad (picture) starts automatic when clicking in a (integral number) field.

How can we disable this? We want only use the default windowsCE Keypad.

Thanx André
