OS: Windows 7 - 64bit
When creating a contact sheets using a footer, the preview isn't updated when adding a footer.
Effect: Irritating user interface.
To reproduce:
1. In XnView browser select multiple image files.
2. Select Create » Contact sheet
3. In dialog "Create contact sheet" check "Footer" and enter some text.
4. Switch to "Preview" tab.
Actual behaviour (bug): Preview tab is displayed. The preview is shown without footer.

Expected behaviour: Preview tab is displayed. The preview is shown with footer.
Note: When checking "Header" and the preview is updated and contains both header and footer. Looks like setting footer doesn't trigger an update of the preview.
