Whenever a page change is made in the console window, all playback buttons (including the master play button) become inoperable and their indicator/feedback lights go off. The modifier keys lights stay on. This problem has been occuring intermittently for at least a year, but now it happens every Sunday and programming time. Changing the default cuelist or restarting the software restores function to normal, but another page change will activate the malfunction.
Please help resolve as soon as possible.
