I have been using powerdot on my Mac Powerbook with TeXShop for about two years and love it. I have just upgraded to a MacBook Pro (the brand new Core 2 Duo ones), and something bizarre happens to the output files from powerdot. The .pdf files generated are strangely distored with blank space through the middle. I have reinstalled twice (and reinstalled xkeyval), but nothing has addressed the problem. Has anyone else seen this, and is there a cure? Todd Kemp.
