I cannot get the command: Switch File -> Switch Header/Implementation to work at all on Mac build 2076. Neither the keyboard shortcut (on mac cmd + alt + up_arrow), nor selecting the command from the menu does anything at all.
I assume this works in the same way as Textmate, where, for example, if you have both header and implementation files open in tabs, and issue this command while one of those files is the active tab, it will switch to the other file.
Any suggestions on what might be the problem?
Thanks.
