KIWIIANO  Simple basic interface, should work a treat, but it stalled with my first attempt, possibly because the text file I wanted to encrypt was too long. I'm not sure.

A Readme describing the options and limitations of the app with explanations of any cryptic alerts would be a big help.

I'll keep trying, this could be a useful program.

KIWIIANO  The Unit Converter installed with Tiger/Leopard only includes US weights. Quite a few folk out here would like to have Imperial weights (for e.g.). Being able to insert you own values would be quite useful as an alternative to the reduced subset provided with OSX.

iConvRate's BIIIG problem is that you can't save your Custom conversion. You only get one and any additions overwrite it.

Maybe v2.1 will sort this dramatic oversight. ;^)

KIWIIANO  Appears to work, but I ran into fish-hooks. My MacBook's TM ext drive initially refused to mount when plugged into a G4 iBook running Tiger. When it did mount and I successfully instructed the MacBook to access it via Airport and ethernet, TM started to recreate the backups from scratch then ran out of room. It's a nominally 160GB drive to back up a 120GB internal with about 84GB used. The 160 already had TM files on board but when mounted as a networked volume those files were ignored. I suspect that the network drive required for TM is better attached to a Leopardised Mac. The drive mounting process seems a bit random and may cause the network connection to hang.

KIWIIANO  Phew has been a killer utility for me. I've got a Philips digital photoframe that doesn't like Macs. Each image alternates with a mystery file that plays meery hell with the slide show and the memory card capacity (metadata of some sort??)

But image files backed up to my SD cards with Phew don't have the extra components, so I get full capacity and clean slide shows. Yaaaaay!!!

(This might be a problem for backups where that 'metadata' is important. )
