cgminer + NVIDIA crash

[Ryu.Hayabusa]

Wish I could post this in the relevant topic but, oh well, maybe someone here has an idea.

I had a few systems available with 3xGTX590s (2 in SLI, 3rd not) but each time I tried to run cgminer it would crash and Windows (7) would ask me if I want to close the application or debug it.  Is there a limited number of GPUs that cgminer can handle on a single instance?  I can run 6 separately using -d0 -d1 etc, but that is annoying and is why I liked this program so much since it was able to automatically run on all GPUs available.

Systems with 2-3 GTX580s (or lower series cards) seem to work fine so far, even with SLI enabled.

If anyone has any suggestions to try I would be grateful.

I dont thnk there is not any restriction for number of GPUs in CGminer, i am using Ubuntu system with Cgminer 3.2.7 where number of GPUs didnt made my program crash,

By far i am sure you have already solved this issue of yours.  I have similar issue regarding cgminer for altcoin(fork of ltc ) which i created for learning purpose. When the block is formed it gets rejected giving the reason of Diffculty, but why the senario is weird is because i have set the difficulty to be as low as possible i.e 0.002 approx, normal cpu minning is working properly and generating blocks with some lag in conformation time but CGminer is not even meeting the difficulty. I would appericate any help or advice
