I'll try downloading again in a bit, it's not available yet. Besides the things I mentioned previously, it can't send commands yet. I tried selecting one of the options on my Magnova driver, and got this error:
Just because I say I have fixed something, do not mean I did a new upload!
I started by copying the regular combobox control and then modified it, I missed one modification

This time I have uploaded a new test version, with hopefully everything fixed, but it looks like I cannot get the color in the comboboxs main window, it changes back to standard after I had a chance to modify them

but any icon will survive.
If you design any icons, be careful with the fileformat, a small file is rather important or the definition will be very long.
Note: the control is not finished and I may add a parameter more.
