You can run multiple beta instances like you can do with the preview build (would be a bit silly to restrict that in betas but not preview builds
).
OK - well, when I tried to invoke a new instance nothing happened. I then reasoned that perhaps there is a box or something in the options dialogue that needs to be checked. In Main Menu > Options > Preferences > General > I saw a unchecked box labeled "
Allow multiple instances (this can cause data corruption)", checked it and closed the dialogue. The attached image of a popup appeared. I was in no mood for taking this 'leap' and cliked "
No".
If there is another way, I am all ears. Maybe doing a separate beta install in another directory (is this what the popup suggestion refers to and is it safe?)? I will defer to your advice.
