This may be caused by a software conflict with GISTOOLS, an ArcObjects application written by Lockhead-Martin. The customers who have reported this problem work for the Central Intelligence Agency. One has had GISTOOLS installed on their computer, but had it uninstalled. The other user currently has GISTOOLS installed.
No solution is known at this time because uninstalling GISTOOLS did not resolve the problem for one of the two customers reporting the issue.
