Not sure if anyone else has experienced this and it may be because I'm on version 5.6.0 of the framework using version 4.0.3 of the announcements module, but...when Oliver Hines Weather module (verision 2.0.1) is used on the same page as the announcement module and a user enters a zip code to lookup, it breaks the announcement module with this logged:

InnerException: Must specify valid information for parsing in the string.
FileName:
FileLineNumber: 0
FileColumnNumber: 0
Method: System.Enum.Parse
StackTrace:

Just an FYI.
