When you are typing in vbCode, why is it that there are some things that are coloured when they are not supposed to be coloured in VB. (and vise-versa).

Code:
Enum         ' This should be coloured

' The following should not be coloured
Randomize    
Timer       
Rnd         
Mid         
Left         
Right
There are some more but I cannot thing of them right now.
