I don't think I ever (consciously) configured anything with Directory services. My computer is not on a corporate network.

I have no idea what Xcode is and why I am running it.

I do have a wacom tablet attached and an external Lacie drive.

Tomorrow I will try to run things without the tablet and Lacie.

Interestingly enough, I forgot about the fact, that the tablet sometimes just gets turned off in the middle of running. Maybe I should trash everything related and reinstall the driver?

I just found hard drive>library>startup items>tablet

is it where it shouldn't be?

Xcode is an Apple application used by programmers. It's icon is a blue rectangle with a hammer on top. It's not something you would run by accident. That message I referred to seems very strange then.
Please launch the "Terminal" application (under /Applications/Utilities) and copy & paste the following commands, press Return, then copy & paste the results back here so we can see:
ls -l /Developer
echo ---------------

You definitely should check on the manufacturer's web site to see if there is an updated driver.

maybe I did something wrong - I copied and pasted and hit return and got this:

Also, I looked for xcode in finder and nothing was found.

No - you did it correctly.
What you got ("No such file or directory") is the result I expected. It shows that you haven't got the developer tools installed. Xcode is one of the developer tools.
So don't worry about it, although I still find that message that mentioned Xcode very strange.

More to satisfy my curiosity than anything else, maybe you could launch the "Terminal" application (under /Applications/Utilities) and copy & paste the following commands, press Return, then copy & paste the results back here so we can see:
locate Xcode
echo ---------------

Yes, most definitely. There have been other cases where the Wacom driver caused significant slowdowns. First remove all traces of the Wacom driver and see if the slowdown problem goes away.

If it does, then you know where the problem is. You can check for an updated driver: http://www.wacom.com/productsupport/select.cfm and see if that fixes the problem, or else you will have to decide which is more important--a correctly working computer or the tablet.

I will see if it's the tablet. But I don't understand why when logging in as a different user, it's not slow at all and the tablet works just fine.
Unfortunately, both correctly running computer and tablet are important, since I do lots of graphics.
The current driver I have is version 4.77-8. Can I download 4.93-3 or do I have to go sequentially through 4.79-2 and 4.91-3?

You don't have to go through drivers sequentially--just go to the most recent driver.

Trevor

It is probably an interaction between the tablet driver and some preferences that you have set for one user and not the other.
In any case, you definitely should update to the latest driver.
As a general rule, each time there is a system update you should check a week or so later to see if there is an updated driver for all of your 3rd-party peripherals.

Sorry guys that i pitch in, but i've got the very same error message
