ISSUES ADDRESSED BY THIS UPDATE 
===============================

This is an update to the files amgdim.arx and amg3.arx to address some issues which were introduced to Mechanical Desktop 5 and Autocad Mechanical 2000i with Service Pack 4 applied.  

The issues which affect both products are:

- A crash that occurs when running a VBA routine that modifies a dimension which had a break applied by the AMDIMBREAK command. 
- The dimensions applied to the inside of a 2D shaft with AMAUTODIM would display the wrong value.
- In the AMPOWERDIM dialog the degree symbol wouldn't display properly under some non-english language versions of the program.

The issue which only affected Mechanical Desktop 5 is as follows:
Attempting to create a blind or through slot feature would result in the product crashing.

Miscellaneous Notes

This update is specifically for the amgdim.arx and amg3.arx files.
