Keith, I updated to the 64-bit version of Java 1.8.0_40 and can't get BB to compile using Ant. Here is what I get: c:\BrailleBlaster>ant Buildfile: c:\BrailleBlaster\build.xml init: compile: BUILD FAILED c:\BrailleBlaster\build.xml:25: Class not found: javac1.8 Total time: 0 seconds c:\BrailleBlaster> Best regards from Ohio, Vic
