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?
