Kensington mouse and Leopard, no control-scroll zoom function

Question

I see that this was discussed a year ago.
http://discussions.apple.com/thread.jspa?threadID=1204297
The Mouseworks driver is the same one--no update!
Anyone have a solution? It was nice to be able to control scroll wheel and zoom the screen from time to time. Is there a 3rd party mouse driver that works with the Kensington mice?
Thanks!

You should find the software at path /Library/PreferencePanes/MouseWorks.prefPane -- that is in the root level Library folder, not a Library folder in a user's home folder. Any items in /Library/PreferencePanes/ should show up in "Others" in System preferences -- that much is normal.
The actual OS extension software that drives the trackball at the hardware level should be at path /System/Library/Extensions/KensingtonMouseDriver.kext.
The freeze is not normal. On my iMac G5, which has the MouseWorks software installed, the pointer responds during boot as would any standard USB mouse's pointer until the OS loads the MouseWorks software. At that point, the MouseWorks settings for buttons, acceleration, etc. kick in. This is very noticeable on my iMac because the acceleration setting in MouseWorks is much higher than the normal mouse tracking speed set in the Keyboard & Mouse system preference.
You can check for the presence of the MouseWorks software using System Profiler: Open that application & click on the "Extensions" item in the list at the left of the System Profiler window. You should see two items in the resultant list on the right, "KensingtonMouseDriver" & "KMWUSBHIDMouse." Clicking on each of those in turn should produce info in the bottom pane of the window something like this:

Following the same procedure, but clicking on the "Preference Panes" item in the list should generate something like this:
MouseWorks:

Identifier: com.kensington.mouseworks.prefpane
Location: /Library/PreferencePanes/MouseWorks.prefPane
If you do not get something very similar (especially for the locations), it probably means the software has not been installed properly.
