I click the "Keep remote directory up to date" button, then I click "Start". It does "Comparing" for a while, then the "Keeping remote directory up to date" window sits there watching for changes. Then I click "Minimize" and it all goes away. This all works fine. But at this point, when I change a local file in a different program and save it, a WinSCP window briefly pops up saying it is copying or something (it happens so fast I can't read exactly what it says). The file copies fine, but that window popping up is really distracting. It didn't used to do that.
I'm using version 5.1.0 (Build 2625). I don't remember the previous version that worked correctly. It was probably the 4.3 branch. I'm going to switch back to that version until this is fixed.
I was scp'ing to Ubuntu 10.04. I'm using Windows 7.
