That seems strange. As mentioned, this is handled by OS X though and isn't under Alfred's control. If you do find a way to reproduce it though, please let me know. I'd be interested in taking a look at it.

I think I just found a way to reproduce it.

The issue occur when you first type something in the address bar of the Safari, without press enter.

Then use web search in Alfred, I won't create new tab in Safari, a new window is created instead.

I'm using 10.9.4 and I agree the new window is created in a rare case, and is hard to reproduce.

But in the case that a new window is created, the new window is created again if I close the new window and search the same keywords with Alfred. However a new tab is created instead if I search different keywords.

By 'randomly' I actually mean it depends on the content you search. I just don't know how to reproduce it.

I use google search with Alfred, but after I press 'Enter', sometime the searched content shows up in a new tab in Safari, which is what I prefer. But sometime a new window of safari is created without any reason. What should I do to avoid a new window? I've already set in the preference of Safari 'Open pages in tab instead of windows' to be 'Always'.
