ppk file relocation causing minor problems

I installed WinSCP 3.5.6 sometime ago when I also installed putty and pageant. At the time I had my private key file (ppk) in one directory (let's call this dirA). Some time later I moved the ppk file to a different directory, and told pageant where the "new" key now was located (dirB). Pageant, putty, and WinSCP were all happy with that. Today I upgraded WinSCP to 3.8.2. When I started it, it complained about the ppk file being missing from dirA. And yet it was then able to connect just fine.
After a period of inactivity the session timed out. I clicked on reconnect, and again it complained, and again it connected.
So how and where do I adjust so it no longer complains and just connects?

You probably have the private key file configured in the stored session with the old path. So it complains that it cannot use the configured file. However, then it finds it in pagent and connects with that. If you use pagent, you do not need to have the key specified in the session directly.

Could you point me to where to remove the key stored in the session?

I found it :-) And, yes, that fixed it--thanks.
