Maybe is it time to delete your preferences?

Okay, Sark.
Needless to say, this just shouldn't be happening like this and we have tried numerous methods to recreate your problem without success. Every change with the Transform Path tool is mirrored by the Info Palette.

There is a "slight" difference in the numbers with the Transform Path because the path calculations can 'bisect' a pixel into fractions. The Info Palette will show only the truncated dimension without the fractions. The differences, however, are NOTHING like the disparity you are experiencing (i.e., from 222 px to 230 px). There should usually be only a 1 pixel variation due to rounding off in the Info Palette.

Since we use a Mac instead of a PC, perhaps sPECTre's suggestion would have some effect on this.

Shark, you've given me the impression after reading your posts again that you've seriously tried everything and that you still have this problem. That convinced me that there must indeed be something wrong so I did some extensive testing myself. I deleted the preference file and started from scratch with PS CS on an XP machine.

My conclusion
You're right; the results can be very unpredictable and makes me think that we're dealing with a bug here. Transforming a 50x50px rectangular shape to 300x300px, doesn't always create a 300x300px shape, at least that's what the new values tell me.
You're absolutely right when you wrote: "Sometimes it's right, sometimes it isn't". Transforming a 50x50px to 300x300px shape should always give the same results and not 300.1x299.9px and then 300x300px after we've stepped backwards (ALT+Ctrl+Z) and tried again, that doesn't make any sense.

The option bar might show different values, but I've only found them .1 lower or higher than they should be, but not 8px as in one of your examples. The strange thing is also this: after I transform a shape that is for example 299.9x300.1px to 300x300px it reads 300x300px in the option bar. But surprisingly the info palette still shows 300x299px. \:]
Many times I thought I had a solution, but quite often when I tried my solution a second time, it turned out that I still had the same problem.

I really think that this is a bug , because I can transform a 50x50px shape to 300x300px and sometimes it works, but sometimes it's .1px lower or higher (and that's without changing any other setting in Photoshop between the tests).

I also have found one old newsgroup article in which someone mentions the same problem, but sadly nobody ever replied.

Well at least I know I'm not going mad now. The problem was on PS6 and now PS7, which is why I wondered if it was my system.

I mostly get 1px error, but if you try scaling a shape other than a simple rectangle, it can be quite considerable.

Like you have discovered, if you re-apply the correct figures a second time, all is well.

Will try writing over my preferences as suggested, but don't hold out much hope. Will just have to accept it I guess.
