[petsc-users] Issues with log_view on windows

[Milan Pelletier]

Satish,
Indeed, but I was trying to write it to another drive.
Anyways, that's not a big deal, only inconvenience. I can just use your trick and create a symlink to point to the proper location on another drive.

Thank you all for your help,

Best,
Milan Pelletier
