P: Vanishing Point Interface Laggy, Tools Reset, No Warning Dialog on Escape

[Marc Trzepla]

Photoshop up to date, yet the Vanishing Point interface is ridiculously slow and laggy when panning and zooming.  Extending and resizing the perspective planes is not quick and responsive - there's a lot of drag .. wait ...adjust ... wait...

And Alt-Tabbing out of and back into Photoshop changes the tool selected in Vanishing Point back to the Grid if previously on Clone.  Clicking starts producing another grid until one realizes that you need to RE-select the tool you WERE using prior.

And there's no warning dialog ("I see you've done a lot of grid making and painting - are you SURE you meant to hit Escape?") when closing out the Vanishing Point interface by accident.

And you can't PAN when the image is at 100% or smaller .. which is helpful when you want to manipulate grids that extend beyond the canvas.

Thanks Mark. I can reproduce the last 3 behaviors. In terms of the esc key behavior, that's standard for all filters - and most dialogs in Photoshop (except camera raw which recently switched to Shift + esc to dismiss the dialog). 

For the first issue with lag, how big is the image you're working with? (pixel dimensions, bit depth and color mode)
