There are some known bugs in the program. We're going to try to keep an auxillary list here (it's currently incomplete).
Some bugs can be tracked at: http://open.jira.com/browse/WST
Known Bugs
- Moving pages between surveys. If you try to move a page from one survey to another by using drag-and-drop, it will appear to work, but when you reload the page it will be blank.
Workaround: hold down the control key while dragging to copy the page.
