problems with own EditItem (cMenuEditIpNumItem)

[mhahn at reel-multimedia.com (Markus Hahn)]

Hi there, 
I have derived my own class cMenuEditIpNumItem  from cMenuEditItem. 
It displays 4 segments, seperated by dots. 

My Problem is _SOMETIMES_ if kOk is pressed,  the item  remains in insert mode. 
If so, pressing  kLeft, kRight release this behaviour.  

Explanation: 
Edit mode are  indicated with brakets: 

  "My IP Address                    192.[168].10.3 


int pos               segment counter, range 0-4, greater than  0 means edit mode
int digit             digit of actual segment.  
unsinged char val[5]  container for IP values.  actuall 4 segments 1-4  are used. val[0]  is not used. 
                                      --- unsinged char will be used  as unsigned int 0 -255.
 
  char *value        the actuall string displayed in menu item. 




I have no Idea where the Problem coud be. Of course, the  "ProccesKey"-Funktion gets   the correct  key code. 

for the hole class see attachment.
