"WARNING - cannot open" during multi-file search

[Aeneas]

I just installed version 7 on Windows 7 64 and noticed this new error "WARNING - cannot open" during large searches.
I received the same number of results as with version 5,
so I assume this is a problem perhaps in the Windows kernel.
Is the limitation 256 bytes of pathname, and is there any workaround to allow it to search very long pathnames ?

When a text editor fails to find a match in a multi-file search,
that is a serious failure of the program, and the developers
should do everything possible to rectify such a bug.
