The Advanced section of the Classic preference pane allows you to select a key combination for use while Classic is starting. If a key combination is selected there, Classic will register the keys as being down until Classic is finished starting. This may cause unexpected behavior if another program needs keyboard input before Classic is finished starting.

Products Affected

Mac OS X 10.1, Mac OS X 10.0

Symptom

While Classic is starting, it stops at a MacsBug screen or seems to be ignoring keyboard input.


Solution

When Classic is starting, you may bypass the selected key combination by pressing and releasing each selected key. After the keys are manually pressed, Classic treats them as if they are no longer pressed.
