If your problem sounds common, chances are that other people have had it before you. Faq.txt is included in the distribution archive, and there's a dedicated page in the website, too.

Reading 2xExplorer's documentation is a self-rewarding experience in itself. I'd specifically recommend keyboard.txt which contains some extremely cool trix that are not available via menu or toolbar commands. There's really heaps of functionality packed in the program and waiting to be discovered, which may help increase your productivity even further. If you discover anything that is suspected to be a bug, please let me know. A good description of the bug.
