Hello David,

I had a close look on this and you are definitly right it wont work this way.
Thinking a little bit of this I believe a second condition like you wrote would be the best way to fix this. Because just putting the .T. in the existing statement would have the effect that all changes (although changes on other records not caused by delete) would be updateted what is not the thing that I would expect to happen.

BTW: I would change the Parameter for Tableupdate from .T. to 1, the Parameter is nRows and it is more clear then even .T. works, I know....
