Hello! Somewhat trivial question: When I open a pdf of a journal, it opens in a new window on the web browser (Opera). When I go to open a second article; sometimes when clicking on download pdf, sometimes when pressing "Go" in SFX Ex Libris, it replaces the other pdf. Sometimes I can overcome this by right-clicking on download pdf and clicking open in new window, I can't do this for "Go" on the Ex Libris screen. Anyone else encountered this. Does anyone know how to overcome this? Thanks! Nobahar.
