I'm unable to confirm this bug on Xubuntu 10.04. I just tried running
cpfind from the command line with default settings on a set of 15 16-bit
.tifs with a resolution of 3745x5626 (generated from 5DMkII .CR2 files,
as I presume Brent's images were). Cpfind took quite a while (11
minutes) but ran to completion.
This was on an aging Intel Core2 Duo laptop with a meager 2GB of RAM, so
whatever problem Brent is experiencing, it doesn't seem likely that
further downscaling of the images is going to solve it.
Cheers,
BBB
