Safari search tab not working upon start up
When I open safari and try to use the search tab provided, I get no suggested links and hitting the return key does nothing. Safari still works and websites still load if I open them via a link or finding them with my history.
Additionally, this problem usually only occurs on start up, if the computer was asleep or shut down for awhile and will persist for a good ten minutes or so; if I had Safari open for awhile, this problem usually will not occur.
Any suggested fixes for this peculiar problem?
