Custom chart gallery and range name conflicts

[Stephen Boyd]

When I create a user-defined chart type, Excel seems to copy lots of range
names to the file xlusrgal.xls.
Is there a way to stop it doing this because it is triggering lots of
problems.

It creates a range name conflict when I try to create a new user-defined
chart type, unless I run a macro like:

Sub deletenames()
For Each myname In ActiveWorkbook.Names
myname.Delete
Next myname
End Sub

in xlusrgal.xls

Is there any way round this?

I get this problem using Excel 97 and 2000 (I don't have XP or 2003).

(let me know if this question should have been asked to
microsoft.public.excel.programming)

Thanks
Stephen
