All PDF readers that I tried on SP3 seem to fall short. Adobe Reader: blurry font and laggy scrolling Foxit: touchscreen doesn't work in browser Sumatra: touchpad scrolling doesn't work Is there any PDF reader that works on SP3? Or is there any way to fix one of these issues? Sumatra is the closest to being ideal, since I could scroll with mouse or touchscreen. But it's still annoying that I couldn't use my touchpad.
