Good thought, but I searched the entire hard drive for usehtml and found only one instance of the .pas and .dcu.
Here is the initialization section. HTMLHelpUser := TUseHTMLHelp.Create; Application.OnHelp := HTMLHelpUser.ApplicationHelp; If I place a breakpoint here, it is being executed, but the ApplicationHelp function isn't being executed when initiating Help. My guess is something is changing the Application.OnHelp but I've searched all code and cannot find anything. But after writing this and searching the entire drive for "onhelp :=" I saw the AppEvnts.pas come up in the list and I wondered if perhaps this unit had been added to one of my units, and sure enough there it was in one of my forms. I guess I had at some stage accidentally added the Application Events component to the form and deleted it later, but AppEvnts was still in the uses clause. This apparently does bad things.

An easy test is to delete the pas and dcu of the file you think it is using. It is still compiles, then you have another copy on your system somewhere.
