I found a bug in which the URL list gets truncated after saving or running a
project.  The URL listbox allows me to paste hundreds of lines of URLs, but
the program truncates the list to about 600 lines (depending on the length of
the lines) after saving or running the project.  This results in lost URLs
which aren't downloaded.  The scary part is that you can paste about 1000
lines of URLs, and the program accepts it, but doesn't give you any indication
that it stopped after about 600 lines and truncated the list; in such a case,
you'd assume everything was OK but actually about 400 URLs were not
downloaded.  I'm now limiting pasted URL lists to 500 lines, but this is
annoying.  Please fix this bug.  Thanks.
