Sometimes puTTy/Plink crashes. The workaround appears to be to go to the NetIDMgr and renew your credentials (even if they have not expired).
Sasha: in my desktop computer (Windows XP) PuTTy crashes each time I try to connect to SLAC mashine (centaurusa or noric) with GSSAPI athentication options checked. getting new credentials doesn't help. Sometimes it start to work, but it doesn't last long - in 10 minutes usually it crashes again. For the moment I just unchecked GSSAPI boxes in Authenticaltion section of PuTTY setup (and it works, but asks for password) - but I hope the solution will be found by experts ... .
