Lightroom 4 settings are not carried over to Photoshop CS5

Question

When opening a raw and unedited file using the 'Edit in Photoshop' menu selection in Lightroom 4 the image opens as expected in Photoshop CS5. The images seem to look identical to me. If I then exit from PS without doing anything to the photo I am prompted to save the file. I do so and return to LR4. Comparing the original raw file and the tif created by PS they appear to be identical.
Next, I make some whitebalance, exposure, and cropping changes to the raw image in LR4. 'Edit in Photoshop' opens the image in PS CS5 but the image appears different. Cropping is there but other adjustements seem to me to be lost. Again clost the image without any editing in PS CS5 and am prompted to save the file. I do so and the saved tif appears in LR4 just as it looked in PS CS5. However they are different.
I'm using a Windows 7 64  bit computer.

The most significant point is that the first time you go to Photoshop with an image, you start with one image inside LR and you end up with two - the original image, and a brand new edited version. Generally this is "Edit a copy with Lightroom adjustments"; in other words, something that looks the same as the LR starting image currently does, as a starting point for PS alteration.
Subsequent times you take this edited version of the image back to Photoshop, the Edit In.. feature automatically switches to "Edit Original" as default behaviour. This is so that you don't get a whole family of fresh image versions appearing in LR, and a whole cluster of TIFF files on disk. Just the same image progressively changing over time, as PS work is done.
A PS-edited version seen newly in LR, starts out with zero applied LR adjustments - so it appears at first, exactly as PS has just saved it.
Say (to help clarify this ) you make a virtual copy at this point - and apply some more LR adjustments onto that. You can now see three versions: [1] the starting original which did not go to PS; [2] an untouched version of the PS edit, which has so far been left alone by LR; and [3] another version of the same PS edit, this time with some new LR adjustments overlaid.
If you push the image back to PS for some more editing, save that, and return to LR then both versions [2] and [3] are going to update so as to reflect this later editing. That is because both are deriving their underlying content in a live manner from the same file on disk, which has since changed.
While you are editing any file within PS you are always viewing the actual content of that file. This will naturally look the same as the untouched LR version [2] does. But it will not look the same as the adjusted LR version [3] does - because the live LR settings which cause [3] to look different to [2], are not included in the PS file which they share. They are separate from that - they are being nondestructively applied and displayed on-the-fly by Lightroom only, and in this example, only in the case of one of the two derived versions.
