Dialog box in Runtime

Thank you

When the button is pressed, a window appears. In runtime mode, this window can not be dragged from one place to another (with the mouse).

Thank you 

Hello,

Based on the description and image of your problem, it seems that the pop-up is user created and not in the software or system frame.

The user created screen has the visibility function to be appeared on specific event. That type of object has its specific location in the configuration and can not be move in run time (just show and hide).

If there is a system/ software pop-up like, login/ authorization etc, then they can be moved anywhere in screen with mouse drag and drop.
