Is anybody else using QuickOffice Connect (the $15 one in the market for editing docs)?
Steps to Reproduce:
1). Open QuickOffice
2). Tap "SD Card"
3). Hit Menu and select "Create"
4). Pick "Word Document"
5). Start typing some stuff
6). Hit Home
7). Long-press Home and select QuickOffice
Your changes should still be there. Now run some other programs, do some browsing, etc and come back - your changes will be gone and you'll just see an empty document.
I emailed QuickOffice tech support and they say that they are unable to reproduce this problem.
