Error Message - Invalid floating point operation

Post by ColinT » Fri Aug 04, 2006 8:09 am


When moving about the viewable screen, I keep getting an "Invalid floating point operation" error message. This only appears to happen in one area of the screen but as the program fails to draw the family rectangles, I cannot identify the offending record or records.

I assume that there is something wrong with the screen co-ordinates in one or more records but how do I recover from this?

I think the error first appeared just after I had completed a "Remove Duplicates" operation

Any answers out there?

It's an unusual error.

As with all unusual errors first try "File | Database | Pack" then close down K&KPro and reopen.

If that doesn't help, then I think you're right about the problem being in the data somewhere.

Printing a Tree Layout report might help if there are connecting lines running off the edge of the report.

If you like, email to all the files from your database which begin "Families." and we will see if any have weird coordinates.

I've had this error before, appears when there are a lot of families packed together on-screen in 1:1 view. The way I got rid of the error message was to spread-out the families (also makes the tree easier to follow), just get close to where the error occurs and move the families outwards.
