Aimster,
If you have the VB6 source, check if your variable "xlapp" is still valid
just prior to the VB6 app's close.
Otherwise there's this, although it says it applies to Excel 2002. It was
last reviewed on February 19, 2005, so it may have a new fix.

Look towards the bottom for "Excel file is opened by using OLE and then
closed but Excel process does not quit".

If there's no different from xlapp.quit, then Application.Quit doesn't
work
either.

And, Tushar, no one makes changes but me, and I haven't made any since the
move to Office 2003. I did notice that alot of the DLLs have been
updated.
I'm about ready to go back to Office 2000, if the company will let me.

One common cause of why XL doesn't close is at
Program won't quit

I have several VB6.0 programs that open Excel, writes data in cells,
closes
Excel several times within a program. This worked beautiful with
Office 2000
without a hitch. My company recently pushed Office 2003 onto our
machines,
and the same programs no longer closes Excel. There is an instance
for each
time it opened Excel remaining in the background. This presents a
problem
for large number of instances. Does anyone know about this change in
Excel?
I've tested it on several machines with/without the new 2003 version.
