of the offending file might help us identify the problem. It is of course entirely possible the ACDSEE just sucks, of course, when it comes to jpeg-in-tiff, and that none of us can do anything about that.

Running "strings" on the IDE_ACDstd.apl (std file format plugin) file from ACDSee 5.0 yields:

C:\> strings IDE_ACDstd.apl
TIFFAdvanceDirectory
TIFFUnlinkDirectory
PhotometricInterpretation
@TIFFReadRawStrip
TIFFFillStrip
TIFFReadRawTile
TIFFFillTile
TIFFReadBufferSetup
TIFFClientOpen
TIFFRewriteDirectory
TIFFLinkDirectory
TIFFWriteScanline
TIFFWriteEncodedStrip
TIFFWriteRawStrip
TIFFWriteEncodedTile
TIFFWriteRawTile
TIFFWriteBufferSetup
TIFFAppendToStrip
TIFFOpen
to fetch tag value
for "ReferenceBlackWhite" array
@LogL16InitState
LogLuvInitState
TIFFInitSGILog
?PixarLogSetupDecode

[... And so on, including lots of zlib, libJpeg and libPNG stuff as well... ]

Now, what version of LibTiff they are using remains to be seen.

My version says "Copyright 2003", and the help file contains a Feb 18 2003 date.

There is no mention of LibTIFF (nor any of the other free libraries they are using) in any splash screen, readme, or help file that I could find.
