Anyone else having problems with QuickOffice saving files that are in DropBox. I can open the files, make changes, save the file and close it. I can see the changes on the PC, but not if I open through QuickOffice. It is like the iPad is loading a "cached" version, not the most up-to-date version. If I go to DropBox, the updated files are there and I can open it in QuickOffice. Anyone else seeing this?
