Re: Disabling clickable header in an NSTableView

Thanks for the help, but I run into another problem implementing your second
idea:

If I override the mouseDown: method, the header is never clickable, even if
canClickInHeaderView == YES.

Anyway, the solution must be to override the mouseDown: method. The
first method
is a little hack and I don't trust it to work forever.
