	I just saw charmm stop in an ususual way that sent a large number of error messages to the screen. I happened too fast to record the details, but I suspect it was this workunit: 1iiq1hvi_mod0014crossdockinghiv1_12646_489996 If so, BOINC restarted that workunit but I'll keep an eye on it. BOINC 6.10.58 64-bit Windows Vista SP2

	It just happened again, with the same workunit. This time, I captured one of the error messages: charmm34_6.23_graphics_window_x86_64 has stopped working details mentioned APPCRASH I'm using a GTS 450 GPU, in case that matters. Is there any way I can turn off the graphics function of that workunit, but let the rest continue to run? Or if it would help more, redirect all the error messages to a file that will be sent back to you, then let it continue to run otherwise?

	Just happened again. I've decided to suspend that workunit for now so I can do something else on my computer, then let it resume just before I turn off the monitor for the night, and let it produce all the error messages it wants to during the night.

	That workunit's now finished, reported and passed the validator. The problems with the screensaver program did not appear to have affected the outputs of the workunit enough to matter, but you might want to try running that workunit at your site if you want to attract more participants.

	Also happening, but less often, with this workunit: 1m0b1hvi_mod0014crossdockinghiv1_14466_117833_0 When I started the graphics manually, I found that the Protein, Ligand, Complex, and Info views ran without problems, but the Resources view caused this problem almost instantly. The four buttons at the buttom for rotations and zooming did not cause problems. Again, this problem did not disturb the main application program.

	Now with yet another workunit: 1m0b1hvi_mod0014crossdockinghiv1_21528_ 335674_0 This many workunits with the same problem suggests that you should look for the cause in the screensaver program of the workunits, rather than elsewhere.

	Now with yet another workunit: 1m0b1hvi_mod0014crossdockinghiv1_21528_ 335674_0 This many workunits with the same problem suggests that you should look for the cause in the screensaver program of the workunits, rather than elsewhere. Thank you for pointing out the issue with the screensaver. We should really upgrade our screensaver but for the moment the person who developed the screensaver left the group and we are looking for a new person. Hopefully for fall we will have new students joining the team. ____________ If you are interested in working on Docking@Home in a great group at UDel, contact me at 'taufer at acm dot org'!

	I've found some information elsewhere about a possible cause for some details of the screensaver crash. It seems that if BOINC starts an application directly under Windows, it will automatically attach certain security descriptors needed to allow BOINC to shut down that program if needed. However, if it is started indirectly (for example, by another application program), this attachment is NOT automatic, and the new application program does not automatically inherit these security descriptors from whatever started it. Therefore, simply moving the mouse could easily not be enough to get BOINC to shut down any indirectly started screensaver program. Apparantly, not all versions of Windows need these security descriptors, but the 64-bit Windows Vista SP2 I'm using is one of those that do.
