Problem with Dashboard since updating

Hi.

I had 1.5 and now have 1.5.2 wordpress.

Previously, when I clicked the links button to format a selected piece of text in the window of a new post page, the links button was set to add formating which made the link open in a new browser. I think my designer set this up. But he’s not around anymore.

How do I set the button so that on default, it adds the ‘open in new window’ criteria to links.

Also, how do I define the directory all my images are in, so that when i press the image button, the directory is there and I just enter the file name. This was set up previously but has disappeared.

Thanks for your time,

Tony.
