Why shrink your screen? #1 reason for me is so that I can print 1 to 1
ratio on a single page and not over several pages providing the actual size
drawing will fit on a sheet of paper.
If you have made your Sketchup window smaller and the tool bars relocate
they can be easily restored by
1. Leave the window with the misplaced tool bars open.
2. Open Sketchup again, you will have 2 Sketchup programs running. The
second one will have your correct tool bar settings locations.
3. Close the Sketchup window that has the misplaced tool bars. You may
save the drawing or not, it does not matter.
4. Close the remaining Sketchup window, the one with the correct tool bar
locations, last.
Basically Sketchup saves the tool bar location that is indicated on the last
Sketchup window that is open when it is closed.
