Hi Sven, Thanks for your reply. My tile cache size is set to 1GB (I have 1.5GB of RAM), which should theoretically help based on your comments. Also, upon further testing I have found that the problem I am encountering seems to be related to the physical dimensions of the image, rather than the file size or pixel count. For example, the GIMP is failing when the height of the image exceeds about 187.5 feet, regardless of whether using 72 dpi or 200 dpi. I would be very willing to try the 1.3x source track. Unfortunately, I am limited to running under Windows at the moment, and my understanding is that 1.3x has not yet been ported to Windows, and that porting would be far too difficult for my amateur level porting skills. Thanks again for your comments.
