slowdown in page drawing

[Tom Ritch]

Since installing sp25,  pages become very slow to draw after a few pages 
have been opened.  It becomes worse and worse as more pages are opened.  
Quitting then restarting OW solves the problem.  A guess is that this is 
a bad memory leak.  I have not seen this slowdown with earlier sps.  I 
saw  the problem at Apple Support Discussions.  After I opened about 10 
pages I noticed the slowdown.  I reproduced the problem with these pages 
but have not investigated any other site.
