Thanks for the reply Sergey. I solved the problem by adding the following code to Textbox.Keypress method:

LPARAMETERS nKeyCode, nShiftAltCtrl
DODEFAULT(m.nKeyCode, m.nShiftAltCtrl)   && Codemine has code that needs to be executed
IF m.nKeyCode = 13
    NODEFAULT
    KEYBOARD '{TAB}'   && Causes Enter to leave field
ENDIF
