Windows 7 Professional, using Google Chrome version 50.0.2661.75 (current version).

The web browser interface with the game is having a major issue, in that when movement commands are entered, there is no feedback from the game, ie you DO NOT see the new room you are in. Navigating requires entering a look command in every room (unless you're super nerdy like me and have some areas fairly memorized). Other happenings are sent back normally (player actions in TSC, creatures entering rooms or attacking, etc), there is just no visible response from movement.

Also the numpad navigation both enters the movement command AND the number in the command line, preventing you from entering further commands until you clear the command line of all the numbers.

Good times, lemme tell ya!
