When playing I often go into the reports area and review stats of other players. On occasion when the mouse passes over a stat pane and the info bubble pops up it will cause HM to completely lock up. It also locks up all of the tables I'm currently playing at, inhibiting me from taking any actions. The little info bubble will be superimposed of the tables even after HM no longer has focus while its locked up. Its happened a handful of times in the past and usually after 30 seconds or so it will un-freeze but this morning it was so bad I had to shut down HM via the task manager and restart it.
