How to freeze SU in UI::HtmlDialog?

Dear friends
When UI.inputbox is active SU freeze. How can we do same in UI::HtmlDialog?

No it is not a problem. Modal means that the window is blocking. You need to close the window to unblock the application. This is what modal has always meant.

This cannot happen. Modality of the window is an OS level thing, not a JS level thing.

You will have to close the window, and reopen it in a non-modal state.
OR … divide the functions between 1 windows (the first being modal, the 2nd not.)

I mean what I said.

Did I misunderstanding again? I apologize if I said something wrong.
