coral poker/ipoker crash/start up issues


i have been playing on Coral poker for a while, and every now and then the client gets disconnected, all my tables close (losing money i had in the pot ), and half a minute later or so they pop back up, having me to click sit back and refill etc. Very irritating and badly coded i'd say. Does anyone else have this problem? I have mailed support, but they have yet to answer.
Also, it takes a long time to start up the client and i usually get the message 'coral poker( or Netbet poker) is already running', and after trying twice it will start up. Is any one else having this problem too
