Sorry, I'm not very technical, but Cyberduck keeps crashing when I try to download a file after changing the destination folder. Also, when I hit the space bar for a (Mac) preview pane, it appears as a half-page, and it's impossible to resize the pane by dragging. Neither of these issues happened until 2-3 weeks ago.
The problem seems to be caused by using the preview facility – ie highlighting an item in Cyberduck and hitting the space bar. This used to work flawlessly, but now (a) the preview window is small, (b) it is difficult to increase the size of the preview by dragging the corner – in fact one can do this in many tiny steps rather than one movement, and (c) it always stays on top of all other Cyberduck windows, and cannot be closed. Once the preview pane has been requested, attempting to download what is being previewed always seems to precipitate a crash.
I did so just now, and the crash report is attached (twice by the look of things – sorry!)
