Two quick issues have been solved in SimpleMarkPPC.
First, the great Cameron Kaiser reported that SimpleMarkPPC did not run in Mac OS X 10.4 Tiger. Well, it ran, but it did not produce any elegantly formatted Markdown text. The culprit was my internal build of multimarkdown which was linked against 10.5 SDK. He compiled mmd linked against 10.4, replaced it in the app, and success. I’ve updated the app download which includes his compiled version for maximum compatibility. Let me know if it works for you.
Second, I noticed a potential showstopping bug in that as you scrolled through a larger document in the “live preview”, the app would keep updating the file even if you had stopped typing. You would keep losing your place if you were reading or checking out the results of your exhaustive MarkDown editing. Part of this relates to the numerous, repetitive disk writes that I will eventually solve, but the other part was figuring out a way to let the live preview have the focus when you were browsing it. For now, I hacked it to work. As long as your mouse is in/around the preview area, it should not refresh. I’ll fine tune this a bit more with testing, but please check it to see if it works on your end.
Oh, and I crafted a simpler, colorful icon.
