Deleting Text causes AV

    Julian,

    Summery:
    I am having a problem that sometimes occurs when deleting text. It seems to happen if the cursor is in a table when you hit the delete key.

    Details:
    This is hard to describe, but I'll do my best. The caps are emphasis, not yelling :P. Start by loading the following document (I loaded into the mini program using WPTools 5.20.8). Next, drag selecting (with the cursor) at the beginning of the first paragraph down to the end of the "LET YOUR CARE TAKERS KNOW ABOUT THE FOLLOWING" section. HERE IS THE KEY: The end of your selection (the final cursor position) needs to be on the same line as the last bullet of that section, NOT ON THE BLANK LINE below the table. Then, let go of the mouse to complete the selection. Then hit the delete key. That process yields the following error (see below). However, if I select from the first paragraph down to and INCLUDING THE BLANK LINE after the section (the line past the last bullet), then it does not error. The error details and WPT source are below.

    I know it is kind of bizarre, but my users are deleting text that way and it is erroring. Any ideas?

    Here is the error:

    exception message : Access violation at address 005D97D8 in module 'ExitDMS2.exe'. Read of address 0000000F.
