I´m having a huge problem working in Blender 2.49b on Windows XP/Vista/7 and it doesn´t happens in MacOSX or Linux, even Linux in the same machine:
pressing Alt+A or moving the Time slider is a pain, even animating the one defaut cube!!! Pressing the Play Timeline button works better, but still bad to work.
The computers I´ve being using have Geforce 8800GTS, 9800GT, 295, etc … with old and after the last dirvers installed. None works good.
If I am modelling, sculpting, etc. It works fine. The problem is changing frames.
So, do someone knows something about it? A way to fix it. I really don´t know what to do! And we need the machines with Windows here to work with Unity and Flash with Blender. All help are welcome.
