Dan, Do you mean Ctrl+Alt+Y and Ctrl+Alt+P? The issue is most likely with the JAWS Key Map file. This is why it's so important to make sure that there is only one Sibelius5.JKM file on you machine. Correct. Even though I had only one Sibelius5.jkm file, I recall having to modify it, or the preference s in Sibelius (or both) so that the keystroke worked correctly. It seems that the hotkey in the Windows menu of Sibelius 5 was not the same as that given in the JAWS .jkm file, if I'm remembering correctly.

This is why it's so important to make sure that there is only one Sibelius5.JKM file on you machine. It's not relevant to the problem that Vytautas is having. His problem is that JAWS cannot find the mixer window at all. I didn't think that this was actually possible because the mixer window is created when Sibelius starts and it always has a unique window class. I'm looking at the code now to try and figure out what's going on.

But with reference the playback being Ctrl+Shift+Y, I had to play with my Ctrl+Shift+P key mapping at one point because I noticed that in the preferences it did not match the window menu hotkey. Is this germane?

This is a serious problen..." Vytautas , Have you tried restarting your machine since this new behaviour began? The only other time I know of this happening was when the user didn't have enough memory to meet Sibelius' requirements. How much RAM do you have?

This is a serious problen..." Hi All, It has recently occurred that I get this message that I've written as the subject line everytime I touch my keyboard in a Sibelius score. I tried opening and closing the mixer window, and it says it can't be opened. What else can I do? Thank you.
