Dollar slips on concern about US economy

It seems that the U.S. dollar is still lingering according to this article. It says "The single European currency rose to 1.3061 dollars in early European trading, from 1.3050 late on Thursday in New York. The dollar fell to 106.38 yen against 106.90 on Thursday." Do you think this is something to be concerned about for the future of our economy?
