System 7.5.3, Telecom 2.3.2, Quadra 840AV & Type 1 Error

After installing System 7.5 Update 2.0 on my Macintosh Quadra 840AV with Apple Telecom 2.3.2, I now get Type 1 errors when opening Fax Terminal and Fax Viewer. This error only happens if AppleGuide 2.0.2 is active.
The issue you describe, which occurs only on the Centris/Quadra 660AV and Quadra 840AV, has been fixed with Apple Telecom 2.3.3. You should upgrade to Apple Telecom 2.3.3 or later, available from Apple Software Updates Web site at http://www.apple.com/swupdates/ .
