PuTTY: App accesses drive with every line of output

I've noticed that every time there is a new line of output in a session (whether it is coming from the remote host or I type a command and press enter), the access light on my usb drive blinks. I'm not sure if the app is reading or writing. Is there any way to disable this?

By the way, to the dev's of this and every portable app: huge thanks for such an great set of tools.

Logging

You have logging turned on. In the PuTTY Configuration window, select Logging under Session and set Session logging: to None.

You're welcome Smile

Sometimes, the impossible can become possible, if you're awesome!

I've not enabled logging that

I've not enabled logging that I can tell. This effect seems to start on its own after the session has been active for some time. I searched the drive for any log files that could explain it, but came up with nothing. I checked the app with sysinternals procmon utility, and it appears that explorer is doing something. Every time I press enter, or some output stops and returns to the command prompt, the following occurs (this is a saved csv file from procmon):

I apologize for the mess, but I'm not sure how else to post this info.

how about paste bin?

How about posting the original to pastebin or tinypaste so we can see it in original format?
