A quick question on the way PTGUI handles EXIF data.  I have just started to use PTGUI and for some reason, the application is not importing the EXIF data that is there.  I shoot Canon RAW, and open the file via Photoshop CS RAW plugin and then save the file as a TIFF.  The EXIF data is visible in both Photoshop and in ACDSee.  Yet, when the imagaes are selected in PTGUI, I get an error box noting that the EXIF data could not be found or processed and I am then invited to enter the data by hand.  Any ideas on why PTGUI is not seeing the EXIF data that seems to be there??
