Do you understand what an alpha is? By definition, an alpha is expected to work in some subset of cases, nobody should expect it to work for every possible use case. Judging from the posts here (I haven't had a chance to try Vortex for myself yet) it works for some people, which satisfies the requirements for releasing an alpha. If you want some guarantee it will work for you before trying, wait for it to finish alpha and get through beta to an official release before trying it out. Otherwise you have to accept the risk that the developers have not resolved your particular use case yet.
