Funny thing : try that out

That used to work properly with Adobe Acrobat ActiveX before v7 !
If you try to include an activeX control in winword.exe , choose Adobe
PDF Reader, then you will not be able to make it properly.

Now is the trick, rename Winword.exe to WinIt.exe and you will fool
Adobe 's ActiveX control, result, everything will work properly. That
means that Adobe has included some code to test wether its activeX
control is running within Winword (same with Excel & Powerpoint) and to
make it fail it that is the case.

Now who is the bad guy....? Spread the word...
