Having Trouble Uploading

I am having trouble uploading and not sure what I am doign wrong.

I am dragging files from a folder into the directory I want to upload to. However, only 1 file at a time is being transfered and they are not being showin in the Transfer Que where I have threads set to 10.

What am I doing wrong?

Also, I keep getting an
[18:05:57] 550 Can't check for file existence
on every file. Anything I can do about that?

Thanks in advance!

You can ignore that error, it's just a check. In order to make drag & drop work with the queue, you need to set "Default Drag&Drop Action" to "Queue" at Tools -> Settings, General -> Navigation.
