jEdit 4.2 and OS X 10.4 worked fine for me for over a year. A couple of weeks ago I switched to OS X 10.5 and a bit later to jEdit 4.3pre13. In the meantime I also updated to Java 6. Since some point (not sure what caused it) I now have trouble with the cursor positioning in jEdit.

Initially, after opening a file in jEdit I can move the cursor and insert and delete text as expected. But within a couple of seconds the cursor position is off - meaning when I insert or delete text it actually occurs one or two characters *to the right* of the cursor position, not directly left of the cursor. This behavior continues until I close the file and reopen it, upon it will work correctly for a few seconds, then misbehave again.

Strange thing is that switching between jEdit 4.2 and 4.3pre15 doesn't help - the problem now appears in both versions. Also, switching between Java 5 and Java 6 doesn't help, either (Info.plist). So right now I can't find any way to fix the cursor behavior - which is driving me nuts.

Any ideas?

Thanks,
