I would try a repair install of SolidWorks.
I think I would have not cloned the drive, just re-installed everything from scratch and copied any needed files off the hard drive. To many chances for odd things to crop up.
I have now removed unticked all addins and it loads much faster, but is still very slow. I believe it is a registry issue or file template destination issue. Hopefully someone can suggest some things to look at.
It would take to long to re-install, everything else working well from upgrade/ disc clone. I don't really want to reinstall.
Computer hardware resource is not an issue as when it is actually running it is much faster
I re-installed Solidworks, that got rid of the slow loading issue but the odd behaviour is still their. No dialouge box for property manger say when adding a plane. It is their for certain commands but vanishes on others and can only use the corner select.
