Quote - Albert Einstein said, "Everything should be made as simple as possible, but no simpler."

We think you're suffering from multiple causation fallacy, a variation of post hoc ergo propter hoc. "This happened after SR3, therefore SR3 caused it."

Often people doing this are unaware of what else happened in the interval, and fail to give any credence to the idea that they've missed something.

The clue is when nobody else can verify the experience.

I have considered that possibility.  I wasn't necessarily saying that SR3 caused the behavior, it could simply have been the installation procedure changing my settings for example.  But I have been using PoserPro2012 almost daily for weeks, so it does seem odd to notice something right after updating.
