Kevin,
please read some of Ron DeBruin's read up on this.
He's done quite a bit.
http://www.rondebruin.nl/tips.htm
look for Excel Ribbon and QAT pages.
Also, the folks over at WROX has posted chapter 14 on the OA-LTD pages.
http://www.oaltd.co.uk/Excel2007ProgRef/Default.htm
When I was making my ribbon I found that the xml portion of the XLAM page
was mis-coded and kept throwing errors.
If those don't help post back, and perhaps Ron will respond.
Best.

During debugging, when I get a run-time error and choose end instead of
debug, my cached IRibbonUI gets reset. Then, when i try to InvalidateControl
I get an Object variable not set error. The only way I have figured out to
reset the IRibbonUI is to close the workbook and then re-open it. Am I
missing something, or is this the only option?
Thanks for any help.
