Background information

During usage, Acrobat and Adobe Reader create temporary files, which are stored in the Windows\Temp and Documents folder and the Settings\[user profile]\Local Settings\Temp folder. Acrobat and Adobe Reader may create excessive temporary files, which can overload the system processor and cause the application to freeze or close. Deleting these files frees up the processor.

Acrobat or Adobe Reader may also freeze or close for the following reasons:
-- The Updater folder or its contents is damaged. Re-creating this folder can resolve the problem.
-- Acrobat or Adobe Reader application files, shortcuts, or registry entries are missing or damaged. Repairing Acrobat or Adobe Reader restores these items.
-- The user account is damaged.

This issue was resolved in Acrobat 6.0.1 and Adobe Reader 6.0.1.
