TC 12.01.44 Working on a small BTM file to learn about the DO command. Searching through the menus looking for a way to have the editor keep my indentation level from one line to the next. Discovered an undocumented IDE command... Edit > Advanced > Tabify Selection. Highlighted my code, clicked Tabify Selection and the IDE crashed with a "Take Command IDE/Debugger has encountered a problem and needs to close. We are sorry for the inconvenience." send Microsoft a report error box. Several tries, same thing. Code can be valid commands or just garbage characters.
