Hi Roberto,
Jeff Davis has accepted it, should be in 4.6 already. Its just a simple html bug. That should display the wizard steps/progress on right side properly.
Also if you would notice in my wizards I resuse the forms in the steps. For example on wizards that needs to pick a content folder. I just use folder-list.tcl on it. So picking an image, page, file or folder uses the same ad_form over and over again. Almost all ad_form are reused, so I have to be careful not to duplicate the state variables names. If I 2 or more ad_forms that sets the same state var then the lastest form to set it will overwrite the previous ones.
