I'm running current compiled with CLANG on the latest stable virtualbox under Win7. It works good, the only issue I had a couple of days ago when compiling world with -j4 (I've a 2-core with HTT) was that the CPUs were not raising their speed. They were just running on 780MHz and the compilation took half a day. A reboot of windows 'fixed' this. Normally if I do such a compile then both CPUs go up stable to 3.3GHz. I suspect that this is a bug in the BIOS or Windows where the frequency control gets stuck. NZ>Let me know if I need to provide more information or if I can help in some NZ>other way. Maybe first try to check with hwinfo what your CPUs are doing. harti
