windows navigation panel error

i think navigation panel may have a bug. one of the programs i was using
wrote the data to a comma delimited generic word and spreedsheet file in the
that specfic program file. when i used the navigation panel to find them they
were not there. when i used microsoftword or spreedsheet program they were
there when i changed the name in the search panel of the word program by
right clicking and then went back to the navigation panel it suddenly
appeared. when i searched for them prior to the name change it found them but
when you clicked on it the navigation panel said it could find the target.
anyone else have this problem?? it appears only when the the program makes
the file. i even turned on all the setting in the view box but no luck. it
only shows after you modify the name.
