Digital BW, The Print

Thank you Stephen for your response.

1)The file is too large to mail (4x5 neg scanned @1200dpi: file size 
400,000K)
2) The file is 'Grayscale'
3) I don't even know what 'alpha channels' are, so I don't think it 
has any of them
4) The original *.psd file had only one layer.

I prepared a second image: ie edit in Photoshop CS and save as tiff; 
then tried to load it into QTR and got the same "Invalid Floating 
Point Operation" error message.

Thanks again for your help...Larry
