To all posting the "clear your cache and cookies" solution, the problem is with the downloaded thick-client versions of the software, not with the web version. Clearing the cache in this case is about as useful as changing the oil in your car. It might need it, but it won't do anything to fix this bug.
That, after at least 2 years, this is still a problem with the software and that no one in tech support seems to have a clue how to fix (or in this case even properly understand) the problem amazes me.
