Hmmm, That's interesting! About the software conflict i mean! All day today i've been trying to find some sort of an answer to my above post, so what i've been doing is trying to replicate the situation of yesterday. Ive now got to the stage where as long as I DON'T exceed a 75dpi render I don't get any problems with 'out of memory' errors BUT I am now getting another strange problem, hitherto un-encountered. I've just been getting problem's with my camera setting's. I tried to alter the 'perspective' setting on my 'Main' camera and noticed that it did NOT have an effect on the scene at all ALSO every time I 'tweaked' the dial all the other camera settings changed as well, another strange thing i noticed was that when I tweaked, the little box at the bottem of my monitor to show that 'Photoshop' was also running would ALSO move left and right with the dial movement at the bottem of my screen??? SO I closed down photoshop, No change. I uninstalled Photoshop from my system and guess what??? Yep NO more problem! Now I posted a while ago in answer to some other poor souls question about a problem and as I said then.. I have had problem's with Poser and Photoshop installed on the SAME system before with Poser3. I had no problems with P5 but it look's like IT'S BACK!!! which is a REAL pain in the ass!!!! Anyway, maybe that help's someone? I've answered myself 2 question's today, 'still can't do high res render's though!
