Problem with 'close' button in Simplified IDEAL?

[Matthew Woehlke]

I'm _trying_ to learn to like Simplified IDEAL... :-)

I've noticed that if I open a class (.cpp), and then its header (.h) 
such that I get split mode, the tab 'close' button always closes the 
.cpp regardless of which one has focus. Is it supposed to work this way? 
Or am I doing something wrong?

Although in all honesty I hate this mode; how do I turn it off? ;-)
