You excuse my english :(, am Italian and have translated this with an automatic translator :RocknRoll: … Blender, formatted the hard disk and from when I have reinstalled windows shows me a few icons of his like a black square :eek: (above all the python icons for the exporters) and in general he turns in the visualization 3D very slowly, not so but in selecting the icons you give cascading menus…
What video card are you using, is it an ATI? also have you installed the latest video drivers from the NVidia or Ati websites? or used the defaults that came with Windows?
I know than the interface of Blender it is completely based on OpenGL and is for sure a problem of video-accelerator card…
Am a few years that i use Blender with this accellerator ( to the beginning, superficially and for “play” and now that i wanted to apply myself just a bit more … ) and passing of version in version up to the current one 2.45, but first had never happened to me, neither with Blender!
