I have a kitchen planner script. I have found that when dragging a combination of doors and cabinets I'm getting errors.
3 different browsers issues are attached.
For those of you with initiative you can log on with username demo(AT)pickabox(DOT)net(DOT)au pw 123456 use the kitchen planner.
Drag a door from "Windows & doors" into the plan.
Then drag any cabinet across the area of the door you placed earlier. This should replicate the same error. If not don't bid, you can't fix what you can't fix.
