2D Hotspot editing, please help

SeaGeoff — Wed, 28 Dec 2005 19:29:17 GMT

Howdy,
I just made a little 2D “ALIGN” object as pictured below. Pretty simple really. I added hotspots for graphic editing and they work fine in my first edition of the object. Then I attempted to revise the object to respond to scale by adding a MUL2 A_, A_ statement at the top. Everything works fine except the hotspots which are now whacko. The object works just as before in 1:1 scale but at any other scale the hotspots at the arrow heads cannot be stretched, the hotspots at the corners send the leader lines shooting off into space. Any help is greatly appreciated.

I can not proof it now, but I think you shouldn't make the "B" parameter movebale. Because this is a special one and is made strechy automatically. The text position parameter should work in your object. Try to substitute the B by a new parameter.
