I have problem for weeks/months with many HM versions. Everyday I can find some tables with no or broken HUD. Most of this problems are at rebuy tournaments. It is like on every 5th table.

For example right now:
iPoker
freezout , 2x rebuy : no HUD at all , after reseat to new table, no HUD
but one rebuy tournament is OK

Bwin
rebuy : I see HUD just for two players and position is wrong
but other tables (FO and rebuy) are OK

Other thing is on 888. They have feature pause all tables because their connection lagging. If they pause tournaments HUD replace all notes with same random one at all players. Have to completely turn off HM to correct that.
