Environment:
Application: OpenOffice Impress
Application Version: 3.3.0
Application Build: OOO330m20 (Build: 9567)
Operating System: Windows 7 Prof 32-bit

Data: N/A

Steps to reproduce:
1. Create default impress presentation.
2. Edit page setup properties for the slide.
3. Set the page width to a value less than the minimum (0.19).  Note:  The minimum is 0.20.
4. Undo the change by click ctrl-z.  Note:  You may have to press ctrl-z twice.

Expected Result:
Undoing the change will put the slide back to it's original defaults and position.

Actual Result: 
The width is set to lowest valid value and then the change is undone.  

When the change to the slide is undone it is observed that the slide is half on and half off the screen to the right of the page view.  This can be corrected by going into the page setup and manually setting another value to adjust the slide to fit within the page space.



It is also observed that the zoom view went to 67% instead of the default 100%.

Isolation Tests:
This can be reproduced using an already existing presentation.
