Go to the nVidia or ATI web site and download the latest drivers for your video card.
Ensure you have the latest version of Quicktime from Apple.
If Steve's suggestions don't work, uninstall the new mouse software and see if that helps. Another poster on these forums recently found an updated mouse software badly affected his PRE.

Thank you for the prompt repsonse. I did update the nVidia driver, but that did not fix the problem. The problem apparently is related to new mouse driver software. I had installed a new Microsoft mouse and updated my software to MS Intellipoint 8.0, reverting back to 5.2 fixed the problem.
Thank you for the prompt repsonse. I did update the nVidia driver as Steve suggested, but that did not fix the problem. The problem apparently is related to new mouse driver/software as you had thought might be the case. I had installed a new Microsoft mouse and updated my software to MS Intellipoint 8.0. Reverting back to 5.2 fixed the problem.
Now, is there anyway to inform Adobe of this incompatibility? I have found nowhere to report bugs or incompatibilities. I was lucky that my old mouse came with a software disk and I had run fine with the old mouse and driver/software. New mice just point you to the MS website. So others may well have the same problem as me, but without an old driver/software to fall back on. Since Intellipoint 8 is much newer, I would hope Adobe would want to have PE9 compatible with it.
Thank you again
I experienced the same problem. I just closed the program and restarted the computer. The blank preview window disappears and the video is visible. It may be a "low resources" issue such as RAM, etc. It works every time!
Thanks for your repsonse, but I did that many times with no effect. But it looks like reverting to an older version of mouse software (I recently installed a new mouse) fixed the problem. (see my most recent post)
