Sooo... New to the game... I can't save. Is that to be expected?

When I click save, I get the dialogue but I can't do anything. There is no cursor. I can click save and it prompts for verification, but nothing happens, I assume because there is no file name entered. I'm not sure what the larger of the two inputs is for because there is nothing in it either. The buttons seem to work though.

Ok, new info. If I click in the smaller of the two boxes, I can enter text (apparently) but nothing shows up when I type. If I click save and then go to load, the save does show up and I can click it and load it, but there is no indication that I've selected anything. It also appears that I can name a save "{space}".

Oh, and in case it helps:

I don't get it. i set up the same ubuntu version and it runs like on windows, well time to delete it and let the Dev's be with you. *giggle*
