it should not manifest itself if only one keyboard is used. the typical 
case looks like this

"keypad-enter" is pressed and the following scancodes are sent

   e0 1c e0
         ^prefix
      ^make code
   ^prefix

as you can see there is no "break" code. "enter" key is pressed and the 
following scancodes are sent

   9c 1c 9c
         ^break code
      ^make code
   ^delayed break code

as you can see, 0x9c is the "delayed" break code for "keypad-enter"

after ukbd(4) patch, the sequence would be

e0 1c e0 9c -- keypad-enter
1c 9c -- enter

i'm not sure. imo, its not likely when only one keyboard is used. you 
could try the patch and see if it fixes your problem. this patch should 
not change anything else and it is pretty safe to try.

thanks,
