Diff does not Open until after I cancel

[hill180]

Really not sure if it is a setting or a bug, but when I copy a file over to the remote server and there is a existing copy, there is a dialog that pops up. 

"The file to be transferred already exists in the destination!"

When I click on "Diff" . nothing happens.  If I click it again, still nothing. but if I click cancel,
both diff windows pop up.

If I just click Diff (Command-K) it works fine but not when in there or when synchronizing.

The Diff function uses an additional connection but it sounds like you have the Bookmark set to only use one and so the additional connection for the diff ends up being queued behind the transfer connection. You need to increase the Max Connections setting in the Bookmark.
