The mini page layout is a nice feature, but it is not consistent. Example: it seems to work for lookup fields on custom objects and when hovering over custom object records in the Recent Items (left bar on Home tab), but not when hovering over record ids in related lists. Why not?? Is there any way to make this work? Note that I am using junction object to link related records, and there is NO VISUALFORCE. Only standard page layouts for custom objects.
I have checked that the mini page layout contains the proper columns. I have also ticked the checkmark for "Related Lists" for "Notes and Attachments". However, when the mini page layout is displayed through the Recent Items left bar, the note/attachments are not displayed even if the record contains notes. Why?
