Glad to here you are still trying some new things. I have tried the latest VEGAn ginger, and Samurai is working fine there now. Such a wierd issue on the current build of vanilla because it works fine sometimes (but jsut randomly). Computers shouldn't be random!
Looking forward to testing the new build.
