Here's a fix to the Windows Missing Portal Records issue at the bottom of this thread:

If you haven't seen it, on Windows, sometimes a portal will show no records even though the records ARE there. Quitting FM and relaunching fixes it for a while.
The attached "ReleaseDebugOn.txt" file with the content "extraflags:no_portal_drs" should be placed in the folder with the FileMaker exe and then relaunch FM.
