gimp 1.2.4 can also load it with lots of warnings by libtiff 
"Compression algorithm does not support random access". (BTW, xpaint 
2.6.8 can also not load a JPEG-compressed TIFF file created by GIMP)

Adobe Photoshop 5.0 Limited edition does not load it with a message that 
the compression algorithm is not supported.

It is located (in German) at Einstellungen->Konfiguration->Bild->TIFF 8 
bit Bildkompression
