I am using Putty to connect to a 7206 running IOS C7200-ADVENTERPRISEK9-M on Win 7 Home Ent 64-bit. Every 15-30 seconds the cursor in Putty freezes. Instead of blinking it stays a solid green. Then after another 15-30 seconds I can type again.

The window is still able to be moved. So, my computer is not frozen. I have tried to assign an IDLE-PC but that doesn't help either.

A week ago I think I read an article that talked about this issue, but I have not found anything since then.

Any suggestions?

I ran across a post where someone else had this problem...

Turn off NTP!

So far, it seems to be working.
