So that we can test it, what is the line you're using for the search box color using RGB values?
There should be no difference in how the RGB values are interpreted for this value compared to any others -- they all use the same code; so maybe you're doing something different for this one?
I'm going to take another look at this. I'm fairly certain that the control has to be custom-drawn (as opposed to just changing the colors), which is probably why I skipped it the first time (the dropdown list is themed).1. Where is the "All Accounts" color located?
Ans: The color of that drop-down box is fixed (cannot be changed).
If you right-click on the header there's a "use optimal column sizes." Alternatively, if you edit the columns and specify one of the columns as "elastic" (the subject column will get the elastic property if you "use optimal column sizes"), then that column will use any unused space so that your columns always fit regardless of the window size.2. Can I remove the blank white column on the right?
I'll take a look at that, too, as far as color.
