Default [Q]

Hi everyone. I am still on 4.2.2. I am rooted with philz touch recovery. I have been having trouble sideloading apps. It used to work fine. I have
allow apps from unknown sources, and usb debugging is turned on.

App installer doesn't see the apk's on my sd card, and from dropbox it downloads, but when the installer asks to install or cancel nothing happens when I hit install. it is totally unresponsive. Yet the cancel button works.

Any ideas? Thanks.
