I have a Mac Pro 1,1 and using Photoshop CS4 and Lightroom 2 with the Wacom Intuos 4 PTK 640. There is a problem with the pen when I select anything and drag, it takes forever to move to its destination or sometimes is will speed up then slow down. What to do?

Hi,
Most of the similar problems occur because of the driver installation or corruption of the driver software. It is simple but in such cases works.
If you reinstall the tablet driver software it may work. Insert the Intuos installation CD given with the device into the computer and install the driver.
Hope this helps.
Hi again,
If you work in Lightroom 2, you should upgrade to Lightroom 2.2.
Some bugs in Lightroom 2 are fixed in that version.
Hope this helps.
The issue is caused by low memory. If you are working with large images, the system drive set as your scratch drive. That would explain how the performance drops only after a few operations are performed and thereafter.
If you don't have a second disk to work with, you might try reducing the number of "Undo" levels to something small like 5 or 2. This will reduce Photoshop's reliance on the scratch disk with the obvious trade-off that you won't be able to back out so easily.
Another thing to do to rule out memory issues is to run the Activity Monitor (in your Applications/Utilities folder) to track the usage of system resources such as memory but also disk, network, and CPU usage.
OR - Easy way - When you see the slow down choose Edit > Purge > All
What the memory configuration in your system ? I mean RAM.
