Each time I open my invoicing package, an error message appears when i open a new invoice or click on a current customer. the message is headed "Alert" and has a yellow triangle with an exclamation mark and reads NSLocationInRange(run,draws)==false. When i click on the OK box, the message does not disappear. Instead another identical message appears. While the message is present I am unable to carry out any other actions. I keep having to force quit and start again until I get a new invoice to work on
