Blender 2.5

Hi, I’m quite familiar withthe 2.49 but 2.5 is really getting hard to get used to. I’m Having problems: 1) I can’t import files in any format into blender 2.5 alpha. After going thru file/import and attach file in the saved format, it does not appear in 3D VIEW. 2) Can I have both 2.49 and 2.5 on my system at the same time?

about 2. - your imported object maybe toooooo small and you don’t see it at 3D view - just try to scale up.
(I have a similiar problems - was very surprised)
