How would I show two canvasses on one window. I created three canvasses(c1, c2, & c3) , and 2 windows(w1 & w2). On canvas property for c1 & c2, I put W1 to see them together. When I run it, it doesn't work, It shows me C1 first, then I hit ctrl-pg dwn, it goes to c2 and then to c3. What am I doing wrong??
