Craftster crashing my nook?

[CamOovas]

So it might just be coincidence, I guess, but I've only had my Nook Tablet for about a month, and Craftster frequently crashes it... I think it tends to be when I click "replies to your posts."  It goes to that page and then freezes when I try to click out of it.  I've tried trouble shooting with the Nook support, but their only advice was to exchange it if it keeps happening.  It took me a while to notice that it was this website, but now that I've started paying attention, it hasn't happened with any others.  I don't know anything about technology so I'm not sure if it could be a problem with my specific tablet or if  other people are having the same problem with craftster on mobile devices  ?
