I have been using P4 for years on my old PC with no serious problems.. it was just annoyingly slow... I now have a much better pc (AMD Athlon 3.2XP, 512mb RAM, 160 GB hard drive and a G-Force FX5500... and an LCD monitor) When I run either P4 (or P5) it suddenly crashes leaving a black screen with the message 'input not supported' floating about, only way out is to re-boot! This can happen after minutes or Poser works for hours and then suddenly goes!... the content doesn't make a difference! I have checked all my monitor resolution settings and they are OK! when Poser works it works well and renders very fast! My PC runs OK with every other program, it is only Poser that does this! Curious Labs haven't responded to my e-mails for help!... can anybody out there help? I am getting seriously frustrated! Bob

I have seen something similar to this before, do you have any USB devices, graphic tablet/mice combinations attached to your computer? I have NEVER gotten a reply from CL, most people seem to, but not me. I am still waiting for a response for question that I emailed this past Friday. I must be on their poopy list. :)

Thanks for the speedy reply... I have a microsoft optical mouse and keyboard and at the moment I haven't connected my scanner or printer... This problem started before I had my LCD monitor, I was still using my old mouse, keyboard and standard monitor.. except then I didn't get the error message, just a black screen! I think maybe the problem is between Poser and my graphic card!! According to my manual the 'input not supported' message appears when the computer is trying to get the monitor to do something it can't! I can't understand why this only happens to Poser 4 and 5 and why sometimes I can work perfectly well for hours!

Well, I gotta eat CROW, CL did respond to my email this evening .. so now I know the answers to my questions. After I posted my first reply, I thought a little more about your problem. I did have the same trouble with a Dell laptop at work. I do not recall what the graphic was but at any rate, the problem occured because I was using a combination of refresh rates, color depths, and screen size that just was not going to work. Hope this helps.

Poser has always been cranky about video drivers so it would be a good idea to check that you have the most recent ones installed. If you haven't installed Poser5's SR4, that's also a place to start.

I once solved a Poser crashing problem on a previous computer by turning off acceleration on the graphic card. Poser doesn't use it, anyway.
