Ok, this is what happens (remote on top / local on bottom):
When the mouse pointer drags over the RichEdit status area and want to enter the remote file list it it placed a bit higher, and a bit to the left. You will recognize that when you drag your file over the RichEdit area to the right, the file WILL be visible at some time, but there is some weird unused "space" when you should leave the RichEdit area.

Red line: Drag the file over the rich text to the remote area, no mouse will be visible.
Blue line: Drag the mouse to the right, and move it into the remote area.
You will see (green dashed line) that the mouse cursor is much higher, and much more located to the left as where it should be. This is also the reason why it is not visible when you are further to the left and then drag it into the remote area, I think.
So far, so good. I think this is what happens.
But now the question to the SmartFTP team is: Why / How can this happen?
