I had a Tiler macro installed in X5 and X6; you can see it here: http://www.oberonplace.com/vba/drawmacros/tiler.htm This is a very handy tool for doing both vertical & horizontal duplicates at the same time (as opposed to just the vertical or horizontal “step and repeat” offered in CorelDraw). Unfortunately, in X7 the icon is disappearing from the toolbar the moment you click on any object that you wish to duplicate. You can get to it manually by going: Tools > Macros > Run Macros > and then select the Tiler macro from the list available. The Tiler window will then appear and function, but how can we get the icon to not disappear from the toolbar, and to work as normal?
I've had the same problem with a few of my tool bar items not working when I've added new things. This has made them work. I find I basically have to restart corel to make them 'active'.
