Comment 0 for bug 761535

I'm trying to set external diff tool (Meld). I use bzr-explorer menu: Settings->Configuration->User Configuration. Here I select Diff tab and add entry named Meld with command meld. Then I press OK. After it meld is used each time I double-click on files in Commit dialog.
But when I close bzr-explorer and start it again it forgets about new diff tool, e.g. Diff tab shows only Builtin Diff.
