Hmmm ... this is the error I receive when launching the color picker using a direct link to http://localhost/appname/CuteSoft_Client/CuteEditor/Dialogs/colorpicker.aspx?type=dialog&file=ColorPicker.Aspx (and in various other places):

Cannot declare a namespace and a type both named 'Siberix.Report.Image'

Considering I am running the file directly this appears to be an incompatibility with Siberix utilities ... does CuteEditor use Siberix?
