Validity check

[Bruce Watt]

I have a file that I get the following message. What do I do about this

Results of Validity Check.
*** Problems were found that could not be fixed! ***

The entity at address 98c87430 has an invalid id (0) destroyed (0)

Any ideas? please

Is it a model with imported 3D elements?

[Bruce Watt]

Thanks Dave for your reply,

There is not any imported 3D object.

The file saves ok but displays the error.

I did a saved as, under a new file and still got the same error.

I decided to just ignore the error and gave it the weekend too sort its self out. By the power of the unknown ( although MS seem to be updating my machine quite regularly at the moment) I have come back after the weekend and started up my machine and I can not reproduce the error in either file.

Many thanks
