This is of genius!!! Thanks for the good advice. If i change and edit your code a little, then it can be used as a temporary solution.
However, this is just a workaround and we will still use the image instead of simply filling the background with the desired color.
Additionally, this does not solve the problem of not being able to change the background for "Listbox", "Editbox" and etc, using the command "/background".
Therefore, I still want to get official support for this functionality, since it would be logical if we could customize a separate background RGB color in any part of mIRC and for each window through a command in our scripts, just like we can do this through the dialog box "mIRC Colors".
