I've found the same thing happening on my Torn PDA app; only thing is, once I open up a player's mini ID/profile, I can't scroll or click or do anything except close and reopen the Torn PDA app. Then the cycle just repeats.
Clearing cache and uninstalling then reinstalling did not work.
Using Torn via browser: I can open mini ID's without it freezing up on me but if I click "New Tab" on their mini ID, it automatically opens the new tab up in Torn PDA.
Follow Up: After uninstalling Torn PDA and clicking "New Tab" on mini ID's in browser, I no longer have any issues.
This conclusion: Sucks because Torn PDA can be very helpful with certain things that the Torn app or Torn in browser are not capable of doing.
