Following on form a thread in the general bit, here is a quick guide to making shapes and arrows in proshow producer.
Basic shapes:
Square: layers tab, editing , then add a new layer ( plus sign) select solid colour, with the same resolution ( ie 740x740 )
Circle, create a square as above, then go to vignette and select shape elipse, type transparent, and everything else at zero
Triangle, create a square, go to crop go to rotate and enter 45% next enter a number in the crop left/right/top/bottom values to bring a box around the solid colour, you can then drag the box down to the required size for your triangle.
Arrows, these can be created with fonts, all of these are with wingdings
Arrow Up, wingding font character é on the keyboard, or hold ALT and type 0233 ( numbers)
Arrow down: ê or ALT+0234
Arrow left: ç or ALT+0231
Arrow Right: è ALT 0232
