Whenever you open the WO on the DC-HTML version, the pop-up window is too big and it covers the current event schedules on the Technicians calendar. You cannot minimize it, nor move it anywhere on the screen.
What is the underlying problem do you intend to solve with this idea?
Potential double booking on the technician you will assign the WO to.
How is the problem being addressed today, if at all?
Look at the available dates of the Technician you intend to assign the WO to before assigning the WO to the tech.
