1) that's how FileMaker does it. I think this is due to FileMaker pulling the valuelist from a field's index--which is already sorted. If this is a single field value list as you have here, you can use an extra pair of fields to get an arbitrary sort. Haven't tried it with checkboxes--I've done it with drop downs, but you can see if it works: Any way to determine sort order for field based Value Lists?
2) that definitely does not look typical. In what version of FileMaker are you working? If 12, what theme? What font? Mac or Windows? One way that you can increase the space between the box and the value is to put a space at the start of every value in the table of values, but this alters the value that will be entered into your field when you select a check box.
3) you can't give a check box formatted field a scroll bar, but you can set up a portal to look and function as though it is a set of check boxes and such a portal can be given a scroll bar.
And a more sophisticated example is found in this demo:
If you are using FileMaker 12, you can still work with these files if you first open them from the File menu to get converted copies of them.
2) FM 12; theme = classic; font was Verdana (changed to Tahoma); Mac
Yeah, a space doesn't sound like the best option.
3) Thanks for the links; I will investigate those.
I'd check all appearance settings on that field, even replace it with a new copy created from scratch to see if it makes a difference. I don't have a Mac, but the attached screen shot is on a classic layout with verdana on a Windows XP system.
Any Mac users want to check this on their systems?
