Have the conflicts in <File> been properly resolved?

This message has the following cause and solution:

• You have attempted to check in a file changed from the current version stored in VSS.

  This warning message often is displayed when you have checked out the same file to more than one user or computer. It is displayed so you can be sure that any merge conflicts have been resolved. In some cases, this warning may be displayed even if no merge conflicts occurred. If this occurs, click Yes and continue with your work.

  If there were conflicts, and you did not open the source file to resolve them, click No. When finished, try your Check In operation again.
