I poker has been problematic for a long time.
It"s not that long ago, after their IT department had struggled for over a year to resolve the long running " re sizeable tables issue" ( they were practically the only site not offering resizeable tables )
Embarrassingly some kid built a solution in his bedroom and sold it as an external program
There is a long standing thread
HERE that has been running since early 2012.
It is widely accepted that there is a bug in the software that kicks people off the network and sometimes won"t allow logging back on as the system still thinks you are connected to your previous session.
The ipoker support response has always been to blatantly assert that the problem is at user end.
