I'm using JEdit in Windows XP and currently use it primarily for Python and some propriatary language work. What I'd like to be able to do is associate JEdit with certain file types so that they can be double-clicked to open into JEdit. I know I used to be able to do this in an older version of JEdit (4.1 I think) but can't seem to get it to work with 4.2 or 4.3. I also need to be able to set the association app with a custom memory heap as I often have to open very large files and keep my heap set for 1Gb. Any assistance on this is very appreciated.
