OK, a bit sloppy of me, but creating a new window using the go to related table step, I inadvertently made it a modal window with no close box and no close button. Every potential menu item of help to me was disabled.
I was able to open a layout, one of a few I had not disabled, that had a button to run a script so debugger was a possibility. Nope, it would step through but opening the script for editing produced a disabled window. Not good.
OK, the key is to have a menu layout with all of the needed buttons on it.
In the end I had to abort Filemaker which is not something I like doing.
Seems to me that Filemaker Advanced should have some means of bailing out of a locked modal window without no close buttons, etc. Did I miss this? Table view with no buttons on the layout and the three buttons disabled for the window actions.
Is there a bailout for the developer from a locked down modal window?
