Why are the edit and delete buttons disabled?
This is likely because the Function is 'Read Only'. When this happens users can access existing Adaptable Blotter Objects but cannot edit or delete them or create new ones. It might be the case that the item in question can never be deleted (e.g. if its the 'Default' layout).
Why are some rows missing from my grid?
Check that there are no Column Filters applied, or that there is no active Advanced Search.
Why can I not see some toolbars in my Dashboard that other user have?
First check that they have not been closed. You can see the available toolbars in the Dashboard popup.
If the toolbar is not listed there then the Function might be marked as 'Hidden' in your entitlements which means you don't have access to see it.
