Build 315 contains more fixes for issues that have been reported. In particular Build 315 has an improved startup sequence. I discovered that .Net would generate some code everytime you ran Startup Delayer. This meant that on slower computers, it would result in an extremely slow startup.
Build 315 now caches all of this which means .Net won't generate the code when you run Startup Delayer, resulting in a faster startup.
You can grab the build from the Product page or use the Update button in the Options Window of Startup Delayer.
