I'm not sure the process you're going through here...you're in layout mode, you select Manage Database from the File Drop down, select the field, and click Options...?
If that's the case, then I don't know what's wrong.
But if the process is something else, if you don't get as far as the Manage Database... window opening, then my guess is the View drop down, Show-->Sample Data option is checked and the database is trying to calculate the calculation result and taking a really long time.
No, that's it. I checked the View drop down and the Sample Data option wasn't checked.
To top it off, it works fine in FM 14 but not in FM 14 Advanced. I have both on my computer only because I started with FM 14 and then it was suggested I get the Advanced. I haven't uninstalled FM 14, but that shouldn't make a different, right?
