[Date] November 2010 [Issue] After a significant number of apps have been added to a page, they can no longer be dragged and dropped to a new location on the page. [Workaround] Delete the app, and then re-add it to the page, dragging it immediately to your preferred location. Note that if you have added any custom content to the app (e.g. My Bookmarks), those customizations will be lost when the Application is deleted. [Response] 
We have reported the issue to Liferay and are awaiting a resolution.
