I haven't encountered this with a recent version of Filemaker, but I have seen cases where file and/or layout corruption was tolerated on one platform and not another.
Here's a fairly quick test you can try.
Recover the file and see if the recovered file crashes. (Test it even if the recover process reports "no problems found...")
If the recovered file works, then best practice is to replace your current/damaged file with an undamaged back up file.
Thanks for the prompt reply, but I had already tried this. Still no success on the XP side using recovered files.
Any other ideas?
At this point all I can think of is to go back in time and run each successively older revision in XP until I find one that doesn't crash and recreate from there. The last resort would be to start with the revision I first began work on 3 days ago.
*Sigh* - once again I am reminded why I prefer to work in OSX.
I got lucky and found a revision that was only a half day's work to update. What worked was to author in the Windows environment.
Thanks for the help!
