MORE INFORMATION

Steps to Reproduce Problem

1. In Developer Studio, create a new text file with the .for extension.

2. On the first line in column 1, type the following and save the file:

   !MS$FIXEDFORMLINESIZE: 132

3. On the next line, press the TAB key to move to column 7, and type the character x repeatedly beyond the 132 column mark in the editor.

4. Press the ENTER key to get to the beginning of the next line, and then press the UP ARROW key followed by the END key to get to the end of the text you typed in step 3. This causes Developer Studio to either hang or generate an Access Violation.
