An error (see attachment) occurred after I tried to change which links should be downloaded.
(This error only appeared once, I can't reproduce it anymore)
Did you close the window just after it appeared?
No, I waited a few seconds.
Maybe I have not waited long enough though, because the site I tried to download contained about 450 links on the start page (i.e. the page you type into the "enter URL"-Dialog).
Later I tried to download the page again, but didn't change which files to download (i.e. make Getleft download all files) and it worked without problems.
