Solution 1: In EBSCO databases, exports often do not open new windows when they should. This usually happens when exporting individual articles. The workaround is to select the article, then export it using the folder export function, rather than at the article level.
Solution 2: Check to see if your browser is blocking pop-ups, and allow them if needed. Refworks exports will often open a new window.
Periodically RefWorks may slow down dramatically, especially when you are attempting to log into the site. There is no workaround to this; the only solution is to wait and try again later.
