when i type it looks tiny, but reading it here, it's fine.

i can't figure out how to empty history, i went to preferences and it says history, but when i open it, it says empty cache, and under tools, it says history, and it has 100s of games, and i seem to only be able to delete them one by one, does it show up differently on a mac?

ellieoop: I don't know if it is different on a mac. But in the pc version, you click tools->delete private data... if you click the "details" button in the upcoming dialogue, you can select which data you want to be deleted.

edit: and if you do it like you did it (i.e. click on "history" not on "delete private data"), you can click on "view" (the one just above the history table, not in the main menu) and change the view to "by time visited" - now you won't see the nondeletable folders and you can select all items with ctrl+a. Now the "delete" button should get enabled, and you can delete them all.
