Quicktime playing multiple videos

I've been having this truly obnoxious problem ever since I installed Lion. Whenever I open a Quicktime video or a preview jpeg (and sometimes a Word document) - the last two or three documents I've viewed in these programs also open.

This is the normal default mode for Lion which now "remembers" what documents (files, movies, images, etc) were opn when you last "Quit" each application. Either learn to close the documents before "quitting" the app or turn this feature off. (I.e., deselect the "System Preferences > Personal > General > Restore windows when quitting and re-opening apps" option.)
