When player lays in bed the night passes and at dawn player is sometimes stuck in the bed. Player can chat but clicking leave bed does nothing, pressing escape also does nothing, no keys work except those to operate chat. Player has to leave the minecraft window and close minecraft with ctr+alt+delete and by task manager, or by right clicking on the minecraft icon in the task bar and selecting close window.
Cant reproduce this issue consistently but it occurs enough to warrant a bug report.

Perhaps happening 1 in 7 times sleeping in a bed.
