You know? I had this issue on my parents' computer when I popped Poser on it a year ago while on vacation. They didn't have a Sony Bravia LCD connected to the computer, but it did have Vista. I remember having issues with sliders and the camera (basically, anything that was a click + drag sort of thing) going crazy and suddenly going to values of like 4532% and such.

Amusingly enough, I tried it again a couple of weeks ago at their place, and it didn't do anything.

Don't worry, my advice is not "wait a year and try again"... :)
