Yes, I am running on 11.50 but that video was recorded in 11.41 before the update. I just forgot to report this error when I got them. Same thing happens in 11.50 so I think it is bug from IXEG.... I obviously did try to do drag and use mouse wheel but it didn't work.... I also redownloaded last time but still having same error. Will IXEG fix this error in further update? I am not satisfied with this jet with high price.....
