Huh?
TOPIC
This article describes an issue with the Mouse Tracks or Thick I-Beam features in the Mouse control panel with PowerPC-based PowerBook computers.
DISCUSSION
If the Mouse Tracks or Thick I-Beam feature is turned on in the Mouse control panel on a PowerPC-based PowerBook or PowerBook 190 computers when an external display is attached, the external display image will not redraw correctly. The display will show white boxes or images of the cursor when the cursor is moved. The workaround is to turn off Mouse Tracks or Thick I-Beam.
In system prior to System 7.5.3 these options will not be available in the Mouse control panel. On the PowerBook Duo 2300c this occurs when connected to a MiniDock, not a Duo Dock. Apple is investigating this issue. It is not known when or if this will be changed.
The following computers are in the PowerPC-based PowerBook computer family: PowerBook 5300, 5300c, 5300ce, 5300cs, 2300c. Additionally the PowerBook 200 or 500 series with the PowerPC upgrade card are in the PowerPC-based PowerBook computer family.
