When I use File > Open, then click the "More" button, the menu pops-up behind the file browser.
This does not happen if I select Utilties > File System Browser.
I'm using jEdit 2.6final, on Mac OSX, which has Java 1.2.2.

Report this to Apple. It looks like a MacOS X bug.
I'm now using jEdit 3.0 and the problem is gone for the More button as described. However, I still get the problem when "Command Clicking" on files. Since the behaviour has changed, and I'm using the same OS, it must be in jEdit, yes?
