A60 lateral focusing issue

[Renderman]

Just bought an A60 - have taken about 500 shots in 2 days. I noticed that on several shots the focus is inconsistant horrizontally accross the shot, e.g. I took a picture of my house and while the right side was in focus, the left was not. I noticed that the problem switches sides as well. So far I have only notice it in wide-angle shots. Took a "landscape" pre-set shot (wide-angle again) and it did the same thing.

Is this a CCD problem? Lense problem? Is it an Aperture thing? Has anyone else noticed it?

Thanks,
Renderman
