Changing profiles on any other tab does not affect the macro assignments. If I change the profile while on the Macro Editor tab then return to the profile I was adding macros to, the Macro List reverts to the single '-' and 44 and the assigned macros on the Key Assignment tab have disappeared.
What exactly the Bind data refers to I don't know.
The top line still displays a '-' but the bind total has decreased to 36. I experimented by reassigning 4 macros and viewing the Macro List I find the four macros listed under Macro List with a 2 under Bind. As a follow up to my previous post, I have noticed that when I open the Macro tab the Macro List box (on bottom left) shows a '-' under Macro List and 44 under Bind.
