Otto: Last time I investigated the "maximize compatibility" option was in Photoshop 7. Since there have been changes in how PS operates (layers in 16 bit) it's not that surprising that the results may have changed as well. >From memory, by checking the "optimize compatibility" button you are saving a flattened layer of the image into the PSD image itself. The reason for this is so that if that particular file were to be placed in InDesign, or Illustrator (CS) this flattened layer is what would be visible to the user. By "unchecking" it, this ensures that users placing those PSD files in InDesign or Illustrator will indeed have problems. If you are only using PSD for "working files" and make it a point to pass off only flattened TIFF or EPS files, then it's your choice as to whether you want to use maximized compatibility or not. Each alpha channel, adjustment layer, or layer mask adds some "overhead" to the file. I don't know if it would make a difference if you ran the "purge" command after removing a layer mask (or use the clear history option), but that's something else to test. If you have serious problems, I'd suggest voicing those to the Adobe engineers, as only they have the ability to make any changes.
