Filemaker 11 Crashing
Mac Snow Leopard 10.6.8. Filemaker 11.0v4. Home / Small Business DB. No extras (Plug Ins, etc.) added to FM.
Plenty of Backups but Table Layouts etc. changed recently, i.e. I feel I would have to go back to a quite old backup with previous Tables etc., to try to avoid a faulty version.
Crashing started a few weeks ago and initially I thought it was one of those things. Unable to establish a pattern except it seems to happen more if I am altering Layouts. Having said that, I am fairly sure it happened once when I was actoally in another program - could of course have been a delay after exiting FM. At least once, it crashed and changed names of a few field labels, e.g. Name became Website. It has also happened when requesting a simple Find (Command-F). Can crash several times in an hour.
The following is the start of about 14 pages of the Crash Report.

Any thoughts where I should start?
