I'm trying to use a wacom graphire 3 but it seems to be a little crazy...everytime I hold pressure on the pen as if I'm dragging, painting, writing, a yellow lined box pops up that "ink" then falls onto. When pressure is released, the box disappears. This happens either in finder or photoshop or any other app.
I'm using OS X.3 on a G4 (not very)power mac. This reminds me of windows though!
I have no tablet here to test but from your description you activated the InkWell (handwriting recognition) feature of Mac OS X. You can learn about Inkwell [a href=\"http://www.apple.com/macosx/features/inkwell/]here[/url].
I would go into the System Preferences (under the Apple menu) and see if there's an InkWell pref pane. If you find it, you can probably disable handwriting recognition.
