I have same pb, I have to close the new table on MTT & re-open it for HUD to appear..same with spin, I think it s not always but very often.
Other point, when you close Winamax software and keep HM3 active, when you open Winamax after a night, the tracker is no more connected to winamax (appear in winamax soft / options / tracker in red, disconnected --> so have to close both, open back HM3 then Winamax to have tracker in status 'active'..it s not a very big issue but a bit annoying

I don't know if it is the same for everyone or just for some guys?? would be great to know, ty for your feedbacks
