I've got the latest download of Mach3 and it's working great and I can load up the wizards but any attempt to change the values in the wizard (like for setting the radius of the circle cutting wizard) results in the value getting reset back to it's default after I've left the edit field.

after changing a value, hit "enter" to make it stick.  If you want to save all your settings in a wizard, click "save settings" before closing.

Thank you.
