ESCHW95458   I have used twain sane for awhile now. (Since 10.4) but I have been unable to get this to work in 10.6. I have downloaded all the newest files and loaded them to no avail. (Even on a clean install) I also emailed the developer, but did not receive any response. I can scan from the command line, but when I use the Twain Sane interface via Image Capture, it starts the scan, and appears to get the scan ( I can see the image in the window) but that is as far as it gets. Locks up - spinning beach-ball. Hopefully someone will have a solution.
