World name: Siren

NPC name: N/A
Monster name: N/A
Class/level: White Mage/42
Party or solo: Solo
Race: not sure
in game time: 1:30 pm
Area: Any area
Steps:
1. Get an invite to a party or a free company
2. No window shows up to accept it. I can accept the party join by typing /join but there's no way to accept a free company invite. I have that setting set properly because I can see the loot from chests and can click on it and roll.
