Changing Button "key" width

When I convert and publish an application using webfacing the buttons that 
replace command keys with text are displayed without a problem on the left side 
of the screen.  For example in an application we use the F8=Send Message.  On 
the left side it displays the words Send Message within the defined box with no 
wrap around.  However we have F8 defined within the screen itself also and when 
it is displayed there it wraps onto the next line.  So Send appears within the 
box but Message appears underneath it not enclosed by the box.  I read that 
there were default width and height of 100 and 30 respectively but even with 
those settings there should be plenty of room.  Is there something that has to 
be changed to increase the size or can you point me to the place where I can 
increase what is the default settings if necessary.  Any suggestions?
