Attachments/Links

Hi all, Two minor queries; if anyone can point me in the right direction or has some tips I'd be mighty grateful. 1) Is it possible to make attachments open in new window across the board, based on user configuration? I would guess that the attachments template needs changing for this? 2) Is it possible within XWiki to have a link to a location accessable to the user's system (eg an 'm' drive that is mapped to a network location), and have that link open in a new explorer window, perminantly (ie in conjunction with q1 but ignoring user configuration)? For example, two users "User A" and "User B". User A has decided they want to open files in a new window. User B has decided they want to open files in the same window. User A: * clicks on a file attachment, and the file is opened in a new window. * clicks on a location link (m:\thislocation) and a new window is opened showing the folder contents. User B: * clicks on a file attachment, and the file replaces XWiki in the current iexplorer window. * clicks on a location link (m:\thislocation) and a new window is opened showing the folder contents. I tried searching through the xwiki sites, but could not come up with anything concrete to demonstrate the configurations needed for either...
