Flying Icons in Knoppix?

[ericbakuladavis]

When I click and drag an icon on the desktop, the mouse pointer turns into a document icon to show that I am dragging something. On occasion, I will see the same document icon, several minutes later, fly across the screen on the same path . So, the click and drag animation is being recorded and played back to me several mintues later.

I'm relieved to know more about what's causing it, but I'm still curious. I'm using LXDE and PCManFM. Any ideas?
