I read the suggestion about embedding a visualforce page in a standard layout.  It seems like a great solution for a user story I am working on  I tried it and I am seeing some unusual behavior and I am not sure if it is a limitation on the capability or I have coded the page incorrectly. 

My page contains a pageBlockTable.  One of the columns in the table references another object.  The first issue I see is if there are more than 3 rows in the table, the rows beyond 3 are not displayed although I see them if I run the visualforce page outside of the standard page layout.  The second issue I see is if I hover over the link, the bubble containing the mini page is cut off.

Is there something I should do in the visualpage to scale it?  Or is there something I need to do to the page layout to increase the size of the section where I placed the visualforce page?
