Indeed, things like this are part of the thrill of living on the bleeding edge. :) My second semester class in LiveCode programming focuses on building mobile apps. Because of all the great new features, primarily mobile-themed widgets, in LC 8 I took the plunge and have been using LC 8 for my class this semester. I started with DP12 and have kept updating my labs because each new release fixes important bugs. Overall it’s been reasonably smooth, with just a few irritants. I was really exited when DP15 came out and I installed it in my lab immediately. Unfortunately for me, it was the day before I discussed how to improve graphics performance in mobile apps. So I told them all about ‘set the acceleratedRendering of this stack to true’. It was in class in front of my students that I suddenly discovered that I couldn’t select any objects!

An hour or so of fiddling and testing after class and I discovered the bug was tied to the acceleratedRendering. I submitted the bug report and in less than 12 hours the team had fixed the bug and submitted the pull request. (This kind of rapid turnaround has been typical of my experience recently with v. 8 bugs.)

So the moral of the story folks, is don’t fear the v. 8 DPs! Sure there’s been a little pain, but no fatal, data-destroying problems. And it has helped move v. 8 along a little more briskly!
