Serious performance problem with LyX 1.4.1 on OS X

[Yaron Y. Goland]

When I first installed LyX 1.4.0 on OS X I had such serious  
performance problems that even on my dual proc G5 with 1 gig of Ram I  
could trivially type faster than LyX could print out my characters.  
So when LyX 1.4.1 was released with a focus on performance I was very  
excited. Unfortunately LyX 1.4.1 is as slow for me as LyX 1.4.0 is.  
In fact even on simple documents containing little more than text  
(e.g. http://www.goland.org/webtemplate.lyx) just typing simple text  
is so slow that I can easily out type LyX.

Please note that I made sure to delete LyX 1.4.0 and do a new install  
of LyX 1.4.1 and then confirm that my newly installed program is  
indeed LyX 1.4.1

If anyone has any suggestions or ideas I would love to hear them  
because I depend on LyX for a book I'm writing and as things now  
stand I'm in trouble.

                Thanks,

                        Yaron
