I have installed Vectorworks on a new Macintosh G4 running OS 9.1 and I have a problem with using the tools. When I draw a line I can not see anything happen until I finish and click. The line does not show up until after I have created the line. The same thing happens when I draw a circle nothing happens until I click where I think the circle should end then I see the circle. An dwhen I click on an existing line to select it nothing happens.
