Changed the typed text in the Case lines to lower case and selected Print Preview (remember, the worksheets are set up at 50% for the test - would expect the document to be full screen for a printout full page)
1. Screen is blank (white) with what looks like an upper right border corner line in the middle of the screen ( a black right angle line)
2. Unable to exit Print Preview. Clicking on Close, the screen flashes to the Normal view for about 1/4 of a second, and then back to Print Preview. Basically, Normal view is locked out
3. Visual Basic editor locked - clicking anywhere on screen produces an error tone - nothing else. "Close" option is off
4. Only way to close the workbook and VB editor is control-alt-delete

I didn't save it before testing, so I can open the workbook with the code in its original form

Now what? Should a completely different approach be taken here?

Thanks
