GetOpenFilename has always only supported filtering on an extension. In
your case, the extension is .txt. If you were able to get it to filter
..test.txt, then you were fortunate, but that isn't the advertised behavior -
so you were utilizing an undocumented capability. You use undocumented
capabilities at your own risk since they may not be supported in later
versions.

In Excel 2000, using the GetOpenFileName method you can include a
FileFilter
(the first argument) such as *.something.extension and the dialog box
would
show those files.

Starting in Excel XP that does not work in code anymore. You can
physically
type that into the dialog box under "File name" and it will work but when
it
is set in code it will only recognize *.extension.

Is this a design change or a bug?

Sample code:
----------------
FileName = Application.GetOpenFilename("Sample Files (*.test.txt),
*.test.txt")
----------------
This will not show a file named First.test.txt in Excel XP/2003 but the
same
code will show the file in Excel 2000.
