Quote - I'll start up Poser 7, load a figure...and then mouse over the figure, and Poser dissappears.

Been having that same problem as well. I also have an nVidia card (Geforce 7300GS). Its something with the most recent nVidia releases—175. I downgraded to an earlier release (93), and the problem seemed to stop but I ended up going back to 175 because the gamma, contrast and brightness settings were all off, and no amount of readjusting seemed to help.

Now, seeing that people who have Poser 7 are having this problem, its not a Poser Pro problem; which is what I thought at first.

Now, whats weird is that since re-installing the recent update, I don't seem to have the problem anymore. Keeping my fingers crossed, though.
