I'm using N800, diablo 43-7 version.
Installation: no problem.
Run pb: in window mode gives "Esc pressed" error, and back to prompt immediately. Runs fine in full screen mode.
Run Backup: I have both internal (8 gb with 3 partition) and external mmc (1gb). It only allow me to select mmcblk0 (1GB ext2 partition on internal card which contains my clone). I can't back up to internat fat partition or external card.
Run Bootmenu: My boot menu was wiped out after upgrading from 36-5 to 43-7. After run, reboot, and choose to boot up from internal card (it says mmc6), it fail to boot up (my internal card clone is still 36-5, cloned using install-tool). Do I have to re-clone? I would like to avoid re-cloning because I have installed different apps and configured differently from internal flash.
Run Swap: configured flash bootup to use swap partition on internal card. Reboot and seems ok.

Edit: After rebooting and re-running backup, it now always skip the 'select target' dialog, and displays an error dialog;You have selected to backup all data on /dev/mtdblock4 to Error: Expected at least 7 tokens for --radiolist, have 4 . ..."
