With nothing designed, its not slow. Once I open my app, then its slow. I dont have a complicated app at all. 3 or 4 windows…listbox, some fields on the screen…nothing fancy. Clicking on a field to edit the properties takes a second or two to pop up in the inspector etc.
On my laptop even dragging a control onto an empty form was excruciating, my mouse would travel across the screen at normal speed and the control would follow in slow motion a few seconds later.
OK. I see that now.
Could not reproduce that.
