Dale, - Some, so called 'bugs', affect some systems, but not others. - I too have no problem freely changing from 2.6 to 3.0, - but that doesn't mean that others with different systems don't/can't , have problems.
For instance, - if I change/update my video driver, or even just reinstall it, - I
HAVE to reinstall DirectX. - Others have said that they never need to do that. - But that's no help to me!
One man's meat, is another man's poison, ... we are all different!
