Print Widget Caching

Has anyone else had an issue with the print widget (using 3.3 codebase) where the widget seems to cache a pdf? Sometimes I would come back to a flexviewer sometimes days later and try to create a new pdf map, and it throws back a map created previously. Furthermore, recently I updated the exportwebmap print service to include a new test template and the changes aren't reflecting in the drop down box, despite the service successfully updating on the server. I have been using my own templates rather than the esri provided ones. They have worked fine since I created the service, but won't update to reflect changes when I overwrite or completely recreate the exportwebmap service.

Has anyone else experienced this?

Any help with this issue would be greatly appreciated.
