Move Subwindows on IPad

Is it possible to move subwindows on touch devices with a finger, for example on IPads?
I have subwindows working and moving OK on desktop (chrome) with mouse.
There have been various discussions about this subject but I have not found a reference to a solution.

I too noticed this. Sub-windows are not movable/draggable in any of the touch devices (tried on iPad and Android devices).
Tested on versions 7.7.6 and 7.7.8.
