An update... There seems to be a magic limit of 51 total folders in the Manage Layout window that will actively show up in the Layout Pop-Up menu.
On one of my two DB's I have 54 total folders and the last 3 will not display correctly.
On another DB I have 52 total folders and the last 1 will not display correctly.
When I de-select three of my higher nested folders in the Manage Layouts window, then the bottom folders once again display correctly in each of my DB's.
Can anyone verify this behavior in their environment?
Hmmm, sounds similar to the 255 layout limit in the layout menu of windows systems. If I get time to create 50+ folders in my windows Xp or 7 machines, I'll report back with my findings unless someone else beats me to it.
<Bump> Anyone have time to test this?
I suggest posting to Report an Issue with this info. (You can include a link to here to save repeating yourself.) That way FileMaker can confirm the bug and I can use their confirmation to create an issue in known bugs.
