Eh, I'm afraid I was to focussed on using batchscan to get the image at a single mouse-click. Just clicking the scan-button twice works just fine, without error messages. Sorry 'bout that. Maybe a hint for those who'll try my fu-script: play with brightness/contrast on the IR-image to get a good dust-mask that is a bit black&white. ljm -- (c) ljm @ xs4all . nl.
