Where is the best place to ask support or the like questions about MIST? I asked this the page before and no replies.

I am running Ethereum Wallet 0.5.2 (newest I think) Mist on Mac OSX. (Says Geth under Activity Monitor.) It catches up with the blockchain every time I start it but if I leave it open it ALWAYS falls behind.
It shows I have 8 peers. When I try to send any Ether it just hangs there and then when I exit I get a timeout error.  
Is there a port that needs to be open or something? (I get peers though so it seems like it can connect.)

If this is not the place to ask, apologies in advance, just point me in the right direction please.

Thx,
Its about sharing
