Unfortunately, Ping Plotter sets this association every time you run it, so this is a problem for people that run Power Point. <br><br>Here's the registry key that's causing the problems - it needs to be associated with a PowerPoint type instead. I'm not sure which one as I don't have PowerPoint installed (I guess many techies don't as I've only heard this problem once before and it wasn't brought up as a big issue).<br><br>[HKEY_CLASSES_ROOT\.pps]<br>@="PingPlotter.SaveFile"<br><br>I'm *very* open to any alternate suggestions for an extension. It's tough to come up with one that doesn't collide somewhere - it's really unfortunate when it collides with Microsoft, though!<br><br>Thanks,<br>Pete<br><br>
