Let's try something new then. Open up the Script Editor, go into the Wizards folder, and find mcCvTuningWizard.mcs. Open that and find the UI information (starts around line 132). You can change the values in wx.wxSize ( , ) to make the wizard window larger. You may also need to change the wx.wxSize( , ) in the line below as well. Give that a try and let me know if it allows you to see and use the buttons at the bottom.
Thank you,
