I've had this issue since 4days ago, and I have used TN for along time and never encountered this before.
When I am multitabling with TN2 the mouse automaticly clicks the betbox so u can type in a bet ammout manually, however it does get in the way of call or fold when I use multi stack wich is quite annoying because it also clicks them if I go up or down between tables, alot of missclicks happens frequently that cost alot of money, any idea what is wrong? I have not found any option to disable / enable this, and this is something new I have never seen before.
