Not sure why that should be. I tried it on my version (4.2pre11) on XP and it works fine. What version of jedit are you using?

Have you tried looking at the activity log (Utilities-Troubleshooting) to see if any errors are occurring as you try to 'open with'?

Given that you say the command line
jedit textfile.txt
opens jedit but not the file, I'd say it looks like the problem is with your jedit install, rather than it being XP specific.

Does the problem occur if jedit is already running when you do the 'open with'? (i.e does jedit just seem to ignore the request, or actually respond in some way?)

Possibly a plugin is failing and getting in the way?
What about trying this:
* Close Jedit
* Rename your jars directory (in the .jedit dir or equivalent) to something like jars.skip
* Try doing the "open with"

see if jedit now opens the file.

If it does that would suggest a plugin is getting in the way. Remember to exit jedit and replace the new 'jars' directory that jedit will probably have created with the jars.skip directory back to 'jars' afterwards!
