VS2012 problems with Windows 8 and Unity

Greetings, fellow Unity developers! My google skills have failed me so I'm here to ask a question. When using Visual Studio 2012 Express with Unity in Windows 8, there is a problem I encountered:

Double-clicking a script in Unity's project view opens it in VS2012 without loading the solution. This results in code-suggestions not working properly and each double-click in project view launching a new VS2012.

If I open the solution file from explorer or click Assets > Sync MonoDevelop Project it loads the solution succesfully. But, even after doing that, double-clicks in project view still result in a new VS2012 being launched and solution not being loaded.

The real problem is that the same thing happens if I want to open a script from Unity's console, attempting to navigate to an error message results in unloaded solution and a new VS2012 launched.

I'm aware that there are workarounds. I can simply open the solution once and navigate to exceptions manually, but that is a bit annoying. Before I switched to Windows 8, I've used VS 2012 express with Unity in Windows 7 without encountering this behavior.

Has anyone encountered this problem? Are there any known solutions? Please feel free to ask for more information.

Edit: I forgot to add, I'm using Unity 3.5.6 and Windows 8 64 bit.
