Trouble with using a snap offset on a clip. Anyone else?

I sent in an X3 trouble report about this and got back a status change that says: The problem you are experiencing is most likely a system specific problem or a configuration issue that we believe can be resolved with assistance from Cakewalk Technical Support.
Before I contact Tech Support, I'd like to know if others can reproduce this on X3. My X2 install works OK.
 
Summary:
Snap offset: moving clip troubles
 
Description:

1. Create a new project with one audio clip in one track
2. Turn off snap and move the now time to somewhere in the clip not on any subbeat
3. Right click on the clip to Set Snap Offset to Now Time
4. Turn snap back on
5. In preferences for Snap to Grid make mag strength extreme and turn off all l'marks
6. Make snap be something easy, like "to", 1/4-notes, and no landmarks
7. Place the cursor somewhere in the top half of the clip and try to move the clip to a new snap point

Expected Results:
The clip should be easily moveable to adjacent snap points to line up the snap offset marker to snap points
 
Actual Results:First, when clicking on the clip to start the move, the clip seems to jump away on the timeline. Then, after moving the clip and letting go of the button, examining the clip offset against the snap point, there can be quite a discrepancy, where the snap offset marker is nowhere near a snap point. This last observation varies; the snap offset could be "near" a snap point or pretty far. Seldom "on".

I haven't been able to reproduce this at HQ. Does this happen in brand new projects every time all the time? (Sorry for being so specific)

I was going to try it, but as far as I got was step 3 and Set Offset Time was grayed out.

Grem, thanks for your help. I've noticed it's grayed out for loops/grooves. Maybe that's it?
Edit: thanks Brundlefly, too.
 
Lots of new Notes to Dan:
I've discovered some other important conditions that can mask or exhibit the problem. I've also reproduced the problem in X2.
 
1st condition: if the snap offset is set within a few hundred samples of the beginning of the clip, the left jumping is harder to see, except by zooming in on the timeline.
2nd condition: if the clip is far enough from the beginning of the project, the left jumping doesn't cause much problem with snapping, just with usability. The snapping could be off by a few hundred samples, but that might not be easy to see except by zooming way in.
 
So updating & abbreviating the formula to reproduce:
-Create a project with one audio clip 4 measures long. Align it at M3 B1.
-Turn off snap and put the Now marker somewhere in measure 6, not on a Q note (in the last measure of the clip).
- Set Snap Offset at Now Time.
- Turn snap back on, making sure Landmarks are unset, Q-note resolution.
- Grab and move the clip
 
See that the ghosted clip jumps to the left, all the way to the beginning of the project. If you try to drag right, you need to drag quite a long way, otherwise the clip just drops at the start of the project. That of course leaves the snap offset misaligned because the clip start aligns at M1 B1.
 
I had to drag more than two measures right to keep the clip from jumping two measures to the left. Do other people see this? Zooming in, I found the Snap Offset marker more than 400 samples from the beat.
 
Setting the snap offset back to zero restores normal operation in every way. (X2A or 3B)

I can reproduce also. On my home PC.
