I know what you mean about the logs....i went over them allot myself, ive already tried all of what you are saying, there is no buttons sticking, FYI the same exact thing has been happening with the Dk CR aswell, ive posted about it on many occasions for both these CR's , The mouse is also perfectly fine, no buttons are sticking or anything and the exact same binds work with others CRs, Tuanha, Richie, Millz, Gladi suite Warrior also, its just this druid CR and Dk. Ive tried everything on my end, i also have some people on skype who have the same issue, with CRs just giving up after a few arena's.
UPDATE
Moved the binds away from the mouse completely on my Dk and Druid and the CR has stopped freezing now, But i use the exact same binds on hunter,warrior, GS CR's and those have never frozen, any idea why the Dk,Druid, CR would and those wouldnt? Im happy i have fixed the issue, But i really like those binds on the naga, they are second nature after sooo many years, can you guys possible fix it if possible?
