Visual Studio Crystal Reports Reference Path.

Hello,

I was poking around my Visual Studio project the other day when I found out that if I open the project properties page and go to the "Reference Paths" tab, there is an entry as follows:

C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet\

I didn't put that entry there (or ate last I don't' remember I did) so I am guessing this was added by Crystal Reports somehow. Why was this reference path added? I am only asking because other third party tools don't do this so this seems kind of odd to me. Also, I decided to delete the reference path just to see what would happen and everything worked just fine. Is this reference path really necessary?

Thanks.
