I have been running seti cuda successfully for several months now. I upgraded to 6.10.43 about 3 weeks ago and all appeared to go well. A few days latter I attached to collatz and began cuda processing on that one. Ever since then seti cuda has not been working. I get seti work units, they say ready to process but never start. Collatz continues to crunch away finishing a cuda work unit every 3 hrs or so. I added debug statements to the xml file and am not getting any messages about too little gpu memory. Environment is vista 64b 6 gig, nvidia 9600m gt with 512 mem memory. Any ideas?

It could be because GPU tasks are done FIFO order, and you haven't got to the Seti Cuda tasks yet, or it could be because of Boinc 6.10.43, and the 197.xx drivers (which report less total RAM)
Boinc 6.10.43 has a GPU work fetch bug, it'll report enough GPU RAM to get Cuda work, but not enough is available at run-time to actually run the application without crashing,
