That's the fix I wanted. Oddly enough, I never noticed the problem until I started bundling 1.0.0 with my application. Then I had many reports of it. However, I also started bundling a strip chart widget and it's conceivable that my earlier simpler plots never needed the font cache. > Russell, a good solution for you, not just for this particular > problem, but in general, is to use MPLCONFIGDIR in your application. > This will give you a custom location for your rc file, font cache, > etc....
