problem adding button to toolbar and .ecf file

[robert dugal]

When using an ECF file my exchange client extension is
unable to install a button on the standard toolbar. The
code doesn't fail but the button doesn't get displayed.

If I remove the ECF file and use only the registry, the
button shows up.

Here is the contents of my ECF:
