SOLVED: Chat Bug - Randomly sends without hitting Enter

SO basically the title says the problem, just today I started to get a problem where every time I went to type into chat it would send after I put in like a couple letters or a word. It was like sending as if I hit ENTER to finish my message but I never did. Not having this problem anywhere else, I'm typing this forum post perfectly. Even took apart my keyboard and rebuilt the switch for ENTER and relubed it to make sure. Only started happening today but a restart didn't fix it either. Please help! I can't type anything in party, guild, global or trade chat without this happening...

SOLUTION: Mercury Trade was causing it, had to exit the program and did a clean install.
