In the meantime, to suppress the issues related to permissions, prebindings and caches, could you apply the following maintenance tips and, in between each of themm, retest ?

First level
--------
Close all the running applications (except the Finder)
(1) Could you try to repair permissions
(must be admin)
Launch Applications/Utilities/DiskUtility
On the left pane, select the drive
On the right, select the First Aid (or SOS) tab
Then click on repair permissions and let run; don not worry about messages like " new permissions...."
Quit DiskUtility
Shutdown and reboot

(2) could also download Macjanitor
http://personalpages.tds.net/~brian_...acjanitor.html
and use it to run the maintenance scripts
The maintenance scripts are Unix scripts which are automatically ran on your
Mac between 02Am and 04 am..if your Mac is on at this moment.
I can advice you to run, through Macjanitor, the daily script each day, the week script each week, ..and so on

Second level
----------
(3) Could you also download Onyx
http://www.titanium.free.fr/pgs/english.html
Go into the cleaning tab and use it to clean the caches. use the defauts Onyx offers, do not
clean at this stage the system caches.
!!! Please download the release corresponding to your OS !!!
