To original post from Laurent :

Oh yes ! Zoom is performed imediatly in memory without to allocate more memory space. Previous implementation recompute the whole image to scale it. This way is definitivly wrong !!!

Yes, a 100% button can be done, but for small image (with a size smaller than screen size), 100% zoom value will not work properlly in preview. Something is wrong in preview widget implementation (indeep)

Look screenshot from my computer...

>BTW, it's no more possible to save the unsharp mask parameters? (another bug to >be opened or I'm just lost?) 

Use Load and SaveAs button on the bottom of dialog...
