Short description of error
When a primitive is added in object mode, the operating panel stays grey and properties are impossible to modify.
Exact steps for others to reproduce the error
Go in object mode, try to add a primitive whatever the process is. The operating panel at bottom left (eg Add, cube, add cylindre, ect..) stays grey. If you add a primitive in Edit, mode, it will work correctly. If you go back to Object mode in order to add the same primitive, the operating panel isn't grey anymore, you can modify the properties but it still does not work properly ( it crashes or it switches directly to Edit and add twive the same primitive)
