As the types of files that you analyze diverge farther and farther from ordinary executables generated with common compilers, you may find that you need to take more control of the disassembly analysis and display processes. This will be especially true if you find yourself performing analysis of obfuscated code or files that utilize a custom (unknown to IDA) file format.
