Can't customize toolbar
FMPA 10, OSX 10.4.11
In one solution, if I open the Customize Toolbar dialog, the toolbar becomes grayed and I am unable to add or delete buttons. Icon/text selections allow changes, as does the size selection.
Other solutions work properly.
I cannot discern any differences in File Options, nor would I expect there to be any. These are all standalone personal use solutions: no account, privilege or other menu changes originally created in 8.5 Adanced, always with default options except for opening and closing scripts.
What's the problem? What's preventing customization of the toolbar in this one solution?
