Hi,
I want a use a modaless form, created by main form, and can switch back to main form to do somethig, like this:

 NewForm2(Form2,Form);
 Form2.Form.Show;

but cann't work, thanks for help.
(use KOL v2.88)

Use Applet. In MCK project place TKOLApplet on the main form, and create forms with Applet as parent:
NewForm2(Form2, Applet);

Thanks, it works.
