If you use tabs in Beyond Compare
If you run Beyond Compare in tabbed mode, it can get confused when you diff or merge more than one set of files at a time from Visual Studio. To fix this, you can add the argument /solo to the end of the arguments; this ensures each comparison opens in a new window, working around the issue with tabs.
