I have found another 'behavior' that might shed some light on the problems that I am having. When I do a preview the interface auto selects a large square area covering most of the scanner bed which I then drag/resize to the actual image I am scanning (nothing new here). What I have noticed with absolute reliability is this:
1. If, after the preview, I can see the entire outline of the selection box then the subsequent scan will work. 2. However, If I can't see the entire selection box then the scan will not work. What I mean by this is that often times the bottom line of the selection box is 'off' the window such that I can't see any bottom line for selecting the image area only. If I put the mouse on the bottom of the frame and drag up I can select the scanning area. Does my explaination make sense? I can send screen shots if it does not. It is as if xsane thinks that the scanner bed is longer than it is. It oddly explains why the scanner lamp has completed the scan and returned but the software seems to be waiting for more data and is getting bulk_msg: timeout messages.
