When your WPF menu alignment is wrong

I had a very weird problem where my menus on a WPF application were dropping down to the left instead of the normal to the right.

It turns out it is due to having a tablet setting set to right handed … even though I don’t have a tablet. The answer was found on the link at the bottom of this post.

To fix it:

Press the Windows key + R and then copy/paste the following line of text.

shell:::{80F3F1D5-FECA-45F3-BC32-752C152E456E}

Press OK.

In the Tablet PC Settings configuration dialog select the “Other” Tab. In the Handedness section, place a check mark in the Left Handed option.

Click OK.

Fixed.

How can I get WPF menus to align like the old win forms menu?
