hmm cant preview over wifi here, does the exported version under fldr.de/geck also work ?
could it be my device? but if it is, i dont get why it recognizes the 'on touched' event but only requests fullscreen on double touch, you can see in the capx that i did not do anything on doubletouch
edit: Ashley i just got confirmation from another firefoxos user who has a Flame (developer reference phone) with 2.1 that he also has the bug, i also downgraded again to 1.3 and still have the bug, i think it isnt constructs fault but for further investigation and a good bug report, could you please tell me what exactly your phone says in options->device->software and also try the exported version ?
