The camera bug is being worked on.
If you're in Edit mode and none of the windows are showing up, go to the View menu and start turning on the windows and toolbars. Another option is to right click on the title bar or menu bar and select the ones you want visible from the popup menu.
For the delete key problem, you're just clicking on a part and then hitting the delete key from the 3D view or the Explorer? Is it also not responding when you use Ctrl+X? There is a setting for turning on backspace being able to delete as well. On a Mac, you might need to enable that setting. Can you hit delete once, then wait a sec and move the camera around to make sure it's not just lagging doing the undo save? |
