Derek,

Hey, GREAT job on the v0.59.1.  I applied the new release and everything 
I've ever written worked fine.  The only problem is in the setCheck() 
routine for tree views.  This sample program has a tree view with 
TVS_CHECKBOXES style defined.  Run the program, clicking between the two 
load buttons.  You'll notice that when "Load with setCheck" is clicked 
the check boxes disappear and appear when the other button is pressed.  
I think I found the problem.  When setting the checked state the "state" 
value needs to be:

checked = (2 * power(2, 12))
unchecked = (1 * power(2, 12))

I changed the setting of "state" in setCheck() and the example program 
works fine.

Also, at first glance it looks like you've got the printing issue taken 
care of.  Thank you!

Jonas
