Hello. I get this lovely message when trying to use the mxer. I hit control alt m ad get The Mixer window could not be opened. Try pressing the keystroke Control+Alt+M several times. This keystroke should alternately open and close the Mixer window. If this does not happen then make sure that the keystroke you are using is the same as the one shown in Sibelius' window menu. Press Alt+W and DownArrow to Mixer. The keystroke spoken after Mixer should be Control+Alt+M. If this is not the case then you must change either the keystroke in the Sibelius preferences dialog or the keystroke in the JAWS keyboard manager. Consult the guide for further details. I have not changed anything so what do I do now? If you wish to unsubscribe, send a blank message with the single word, unsubscribe - in the Subject line to: sib-access-request@xxxxxxxxxxxxx
