Does the crash only occur with a specific file?
Test by creating a small sample file and see if opening it and working with it also generates a crash. If it crashes too, the problem likely lies with the computer or it's installation of FileMaker. If it does not crash, it becomes more likely that there is a problem with the file.
What is reported when you recover the file? (The file could be damaged.)
Things to keep in mind about Recover:
- Recover does not detect all problems
- Recover doesn't always fix all problems correctly
- Best Practice is to never put a recovered copy back into regular use or development. Instead, replace the damaged file with an undamaged back up copy if this is at all possible. You may have to save a clone of the back up copy and import all data from your recovered copy to get a working copy with the most up to date information possible.
It's not with just one particular file, it's a completely intermittent thing. It can crash one day using a particular file, but then work fine the next day. I'm assuming this isn't a common problem? Just found it a bit strange that their older version never had any problems, but since moving to this version it keeps happening. Since its been reinstalled several times on both PCs I don't think it's the install that's the problem. Might have to completely reimage one of them and reinstall everything from scratch to see if that fixes it.
It's not a known issue. If it were we'd be inundated with complaints here at the forum.
How do you know that it's not with just one file? (Not trying to argue, just don't see anything in your post to confirm that detail.)
Even if you have several files that are crashing like this, try it with a brand new test file to be sure.
Have you tried recovering the file? Did you test the recovered copy?
Sometimes an older version "tolerates" damage to a file and then the problem isn't noticeable until you upgrade. Changing platforms between mac and windows can also bring hidden file damage to light.
Also, since Exporting data is writing a new file to a hard drive, make sure the hard drive is "healthy" if you have not already done so.
