Version 1.5.6.1
Windows 7 64-bit
I set up a page with three images, each 4800 DPI, approximately 500 MB.
One image is 12.5" x 12.5". The other two are each 5.8".
I tried to export to "tiff".
I could not get DPI higher than 2400.
Working set went to 4.7 GB (computer memory is nominal 6 GB), then message "Error writing the output file".
Did I hit a limitation, or is that a bug?
