Ah, I see that you are working with a Linux version of CCS, not Windows. I wonder if the disassembly issue could be specific to Linux as I had been trying to reproduce it on Windows. Let me try this out on a Linux system and will if I canget back to you on whether I can reproduce it or not.
Regardless of this specific issue, it is recommended to update to the latest version whenever possible. The latest is CCS 5.4 and is available for download at
