From HTG howto instal flash on nexus7
Bear in mind that Adobe hasn’t “certified” the Flash Player for Jelly Bean (Android 4.1) – it’s not guaranteed to work properly and you may see some bugs. Adobe is discontinuing development of Flash for Android.
In other words, Flash isn't meant to run on that device.
Problems are to be expected.
