It is interesting to me that I have no memory of that!  It looks like a 
nice answer to my question (I didn't post the question today, but I 
posted almost the same question in 2005).  The recommended solution is to 
use vncconfig as follows:

vncconfig alwayssetdeferupdatetimer=1
vncconfig alwayssetdeferupdatetimer=0

Will that fix all desktops if run by root?

Can a user of display number "n" do this?:

vncconfig -display :n alwayssetdeferupdatetimer=1
vncconfig -display :n alwayssetdeferupdatetimer=0

Thanks!
