Hi

I have a strange problem with Chimera 1.7. My computer (Windows 7 64 bit) just had Microsoft updates last night and now Chimera does not see any drives but C and D. I usually use files on virtual drives E, etc. I tried rebooting, reinstalling Chimera but it is still the same problem.

Any suggestions?

Hi Larry, Chimera determines whether a drive is "useable" simply by trying to go to that's drive's root folder (e.g. "E:"). Can you try this: open IDLE (in General Controls) type "import os" type "os.chdir('E:')" I assume you get some kind of error. What is the error message? --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu
