New Post: Changes to Wizard theme ignored

Hi,

I'm sure I'm missing something obvious. I'm trying to add margins to the back and next buttons in the Wizard. No matter what I change, it seems like the changes are ignored. Not just margins, but even hardcoding the "Content", or even commenting out the whole StackPanel. I tried this on both Theme files, just in case I was dealing with the wrong one.

Any suggestions?

Thanks,
Michel
