[DUG] Com support

Unfortunately no.  Only using stdOle32.tlb  (which I assume is std).

It has been a while since I have done this stuff but should I (D2007) be 
able to double click a method name in the left list of the 'type 
library' screen and have it take me to the source code?  I thought it 
used to.  I wonder if there is some problem / file missing between the 
type library files and the pas with the methods?
