Wizard MoveTo() ignores AllowReturn=false

[=?Utf-8?B?TWFyaw==?=]

Hi,

When redirecting to my aspx page, I check if user is authenticated. If user
is authenticated I use the Wizard's MoveTo method to skip the first step.
This works as expected only I get a 'Previous' button, whereas the first step
is explicity set with AllowReturn=false. If I navigate through the wizard
from the first step all is fine, i.e. no Previous button. Almost as if
AllowReturn is ignored when MoveTo is invoked! Is this a bug with Wizard
control??
