--- Comment #6 from LIGHTNING UK! lightning_uk@imgburn.com 2011-08-02 15:12:41 CDT --- Ok so my 1st attempt with the patch was marked 'Apply failure', as was my 2nd attempt - so now I just give up.
I'll leave it to someone that know what they're doing.
Hopefully it'll get done sooner rather than later because now I've worked around bug 27559 in my code, people will just end up seeing empty ComboBoxEx controls in my program that they can't do anything with.
