if I click on VIdeo Event Pan/Crop tab it flies down vertically and I can not open, the same thing happened with the Track motion so the advice was to reset Vegas 7 what fixed the track motion issue but caused the above mantioned one- so can not open it -reset does not work?
If it's not docked in the docking area, it sounds like you've moved it "off" the screen. I would try changing to a higher resolution on the video card temporarily, finding those window, moving them back to the main area, and then changing the resolution back.
that or you can save your window layout if you like it the way it is now, then go and click on the default view, and see if it's still happening, if it is, then just re-lay out your windows the way you like them, and re-save over the saved layout that you have.
the new window layout section of your menu is in the Vew list.
