Question about close/show a modal dialog form

Hello again. I have a new problem, if can anybody help...I have a MODAL DIALOG FORM, one (1) TAB-Strip on it, and on the second tab I have a GRAPHIC Button.
When I click the GRAPHIC Button, I want to close the Modal Dialog Form, then I want to pick a point in the AutoCAD window, and another 2-3 commands and after that, I want to RE-SHOW the Modal Dialog Form. ( Similar with ARRAY command with polar option, when is needed to pick the center point.)

My problem appears when I want to RE-SHOW the dialog form. It does not wants appear.

  Thanks.

Hi, Iulian,
