Hi dark1stu
Ok mate I will answer you seeing as the regular guys on here seem to be ignoring a new member
(c'mon Jukejohn, conan, dj, stampy where are you guys ??, a new member of our gang needs help!)
Ok the bad news is you cant modify either the F keys or the back colour, but I will tell you why, you may agree with our thinking or you may want to add your better suggestion to the JBP wish list, here goes...
The F keys are fixed so that whichever software you get JBP, Videobox or KJX, they all work staraight away (plug & play) with our Coin Kit USB Coin Acceptor interface without any confusion or messing about.
The back colours, well that was introduced after a while to prevent the user interface just appearing 'static', I promise you after a week you wont even notice it.
Ok, if you have any suggestions for JBP improvement please put your ideas in the JBP wish list, I promise you they will be considdered for the next update.
