One more thing, I created a Web Viewer and FileMaker was able to fetch the URL correctly. So it seems to happen only from the Import Records script step and menu command.
We're experiencing the same thing. Have you found a solution to this problem?
It works fine in v11, but doesn't work in 8.5, 9, 10 on 10.7.
I'll second that. It broke somewhere in the Lion updates and FM11 is the fix.
