Setup TC the way you want, and then copy and save your tcw18_xml.ini file (if you're using v18) and your desktop.ist files to a safe location. After a crash, you can use these to restore TC the way it was before the crash.
You might also want to make a backup of your cfg file... which will restore your toolbars, menus... etc. back the way you had them.
Just a thought. It's the first thing I do after I have TC setup the way I want.
