I have just recently had this problem with titan, william hill and poker770, started happening 6 weeks ago. Spoke to support 7 times and no joy, after numerous badbeats on cash tables i close software and get error message "playtech client engine has stopped working". After software has closed and i try to reopen i get error message "software (being which ever site i am playing) is still running". So i then look in task manager and sure enough, the playtech client engine is still running. WHY IS IT STILL RUNNING, GOD KNOWS. This only happens on ipoker network. Only thing i could do is contact Antigua gaming commission and ask them to look into it. Will report back when i hear more.
