Hi,
could you please send screenshots of the problematic items?
(Press Print Screen, and the in Windows Paint choose Edit -> Paste. Then you can save the image as jpg file, and then please send me.)
I am afraid, some older graphics hardware cannot handle features AChat requires. You can try to refresh video driver, and we will check also the items (please send screenshot!), but it is possible that only a new video card can solve the problem.
AChat runs well even on a 9 years old Geforce2 MX, but older integrated graphics solutions maybe does not have the required features.
Regards,
tom
