It's weird, when I have a lot of notes on someone, the note popup changes to
{line of note}
donkdndkdndodondokndokdnokdnodknodknodknd
after that HUD crashes and I need to restart it.
the only way to deal with it, is to manualy edit note in HM and by edit I mean delete some of the lines.
I played around a bit here and couldn't get the problem to happen. The next time you see it can you go to the "..Holdem manger\importing\hud data" folder. I'd like to get a copy of the "Site - Table.dat" and "Site - Table.hh" files - where Site is the site and Table is the table you made the notes on. You can attach them to a post here.
