It's very irritating. Portlet size gets changed with the size of browser. How to get control on look and feel of the portlet in this case? The content inside portlet just go crazy. User can keep any size of browser, how to manage this?
A little bit of a control freak, eh? Trying to completely control the layout?
You can do this in the theme, but again, a portlet is just HTML delivered to the client. Surely setting height and width properties at the table and TD level within the portlet should control sizing to a degree.
