OSX 10.9.1 Alfred 2.1.1(227)
If Dictionary.app is left on a tab other than Dictionary, when activating Define from Alfred, the dictionary is opened to the tab it was last viewing, not the Dictionary tab. The behavior drives me mad, as I won't recognize i'm on Thesaurus and quickly become perplexed as to why a word I know should be in the dictionary isn't showing up due to it having no notable synonyms.
