Re: [libreoffice-users] Changing The Mouse Cursor to an HourGlass

Hi :)
I'm impressed.  

It follows the principle of "Release early and release often".  It does the job done.  After 
release clients may make suggestions anyway even if it was 100% exactly following their specs. 

I was suggesting a progress bar instead of the mouse arrow changing to a wheel not as well as.  
Either is good.  I just thought you had run into a brick wall with the mouse thing and needed an 
alternative idea.  You could always try to sell it as "an enhancement rather than a bug" by saying 
it allows people to get on with other work instead of tying-up the machine due to the single app.  
However now you have done the mouse wheel as they asked for then you could always just get rid of 
the progress bar.  The progress bar might be good for a different app or for a different release or 
if the clients change their minds about the spec.  

Regards from 
Tom :)
