Hi Tim,
I don't think I've seen this with my D2W-Apps yet. This may be due to my disabling browser navigation via the page wrapper:
@Override
public void appendToResponse(WOResponse response, WOContext context) {
super.appendToResponse(response, context);
...
ERXResponseRewriter.addScriptCodeInHead(response, context,
"if(window.history){window.history.forward(1);}");
}
This quite effectively prevents the back-button from wreaking havoc. Also, you may want to try:
100 : task = 'edit' => shouldRecoverFromOptimisticLockingFailure = "true" [com.webobjects.directtoweb.BooleanAssignment]

It seems to be due to something left "dirty" or unchanged and I feel like I've seen it when users start using browser navigation instead of the "Cancel" button on an edit page. When they come back later, something is messed up and subsequent saves fail.
