On starting BubbleGEM a BUBBLEGEM_ASKFONT message will be sent to the 
AV-Server or the application with the AES ID 0. This should be 
answered with a BUBBLEGEM_FONT message (Jinnee supports this).

msg[0] = BUBBLEGEM_ASKFONT;
msg[1] = apID;
msg[2] = 0;
msg[3] = 0;
msg[4] = 0;
msg[5] = 0;
msg[6] = 0;
msg[7] = 0;

msg[0] = BUBBLEGEM_FONT;
msg[1] = apID;
msg[2] = 0;
msg[3] = FontID;
msg[4] = FontPt;
msg[5] = 0;
msg[6] = 0;
msg[7] = 0;

If BubbleGEM receives this message, it immediately takes the font with 
the ID msg[3] and the point size from msg[4] to display help bubbles. 
The ID and point size is adopted without checking validity. 
Additionally BubbleGEM reacts to FONT_CHANGED if the corresponding 
checkbox is active in the CPX module.
