Hello Paul,
I have not heard of this issue. It may take seeing the custom ribbon. Also, the best support for ribbons would be to export as a BIN and re-import. There is also 4.11 that is now available and may be worth testing. Here are a few items that I know...let us know if they help.
I think these are best practice for ribbons:
- To retain your custom ribbon from version to version, you need to export it (as a .bin file), and then import it after upgrading.
- When you import the ribbon, it won't include any of the new commands or ribbon tabs, so you will need to manually add them.
Let me know if that helps at all.
Thanks
Scott
