Maximum file list in InfoViewer

Hi Gurus,

My project has grown to a size of more than 58 Dialogs created, more than 59 source and header files.
I noticed in the InfoViewer, 58 seemed to be the limit of files listed.
That is, if you look under "Resource -> Dialog", only 58 (maximum) are listed.
Likewise if you look under "FileView->Source Files", only 59 (maximum) are listed.
WHY ?? is there a way of changing this size ?

By the way, I am working with VC++ MFC 5.0.

Thanks for any help please.
