Hey Guys

Got a workbook which sometimes throws up a run time error if a user fails to properly copy data prior to pressing OK on a popup box which runs a macro. The error is obvious and is not the problem. The matter is that when it happens, other people who use the workbook, press END on the 'Run-time Error' dialog box. This also stops the vba within any open workbook. Ie I have another workbook open at the same time which automatically saves prior to closing when pressing the closing X. But that stops working as soon as someone has pressed END on the run time error dialog box on another open workbook.

Any ideas how to prevent this?

Cheers

Ash
