Web page scrolling disabled whilst a PDF is open in FFbrowser???
Web page scrolling via my laptop trackpad is fine until I go to any website with a PDF and open the PDF within FF. Then I can't scroll with the trackpad till I close the tab containing the PDF. The vertical scroll bar icon with up and down arrow displays next to the cursor but nothing happens. With the PDF now closed in FF I have then opened a PDF with Adobe reader and I am able to scroll anywhere within Windows and FF. This incident is only isolated within FF and does not affect functionality of Windows OS.
I have found that the gestures and finger scrolling don't work correctly in Firefox 8 when you have a tab open with a PDF displayed. For example, Tab A is a website, Tab B is a PDF. When I'm navigating through Tab A, the scrolling function doesn't work on that tab, but the PDF on Tab B is scrolling away in the background. Hope that makes sense!
