Shortcuts not working any more

[Silent_Panther]

My shortcuts are only working for a short time after a reboot. Affected shortcuts are all shortcuts for Expose & Spaces, CTRL + Tab and all screen print shortcuts. Re-assigning is not helping....

 

In 10.5.7 the shortcuts would stop working after the OS was up for around 5 days (sometimes even longer). After the upgrade to 10.5.8 they stop working after a couple of hours

 

I have seen a few posts about this problem w/o a solution

 

Any idea what i could look for / try out?

 

thx,

David

Short update:

It's working fine now for 13,5 hours and it is still OK

 

here is what I have done so far:

- fixed a network error message "_CFGetHostUUIDString: Unable to determine UUID for host. Error: 35" by adding a new entry in NetworkInterfaces.plist

- re-installed AppleSMBios 28

- reverted my background to a standard image which came with Leopard and a standard screensaver (I found an error message in system.log which was written around the time the shortcuts stopped to work)

 

I have the impression that the screensaver with a high resolution image was the culprit. If this is true it had nothing to do with the upgrade to 10.5.8

 

I will continue to monitor my system and update this thread if this is a long term solution

 

Update (09.09.2009):

It's running for 4 days now w/o any problems so it is an issue with the background image / screensaver.

Will try to narrow down a solution and contact others who had a similar problem to find out if it was caused there as well by the screensaver
