Switching back and everything is fine. The Pentium Emulation on the other side works fine! The Application loads but it hangs with 99% CPU usage and ca. 3-4 MB Memory Consumption. Normally, .NET is capable to run on all x86 Processors >= Pentium. XP and non-.NET Apps work fine. Any Ideas what happens here? I also started applications that were NOT started with the QEMU32 CPU to prevent a caching - same problem. Best regards, Erik
