I am often viewing an object model in the Object Explorer, and when i
press F1 to get help on the selected method, a completely grey Help
screen appears. I figure this is because the help file is not where it
should be or named appropriately.

In particular, this is happening with

C:\Program Files\Common Files\System\ado\msado15.dll
Microsoft ActiveX Data Objects 2.7 Library


I did a search for "*ado*.chm" and found many files, including

ADO270.CHM

which i figure is the proper file. Where does this file need to go to
automatically access it via F1 in VBA?
