We've been using POI (most recently 3.10) for a while to create Excel reports and we're suddenly having a problem with a user who recently upgraded to Excel 2013. If they try to open the file directly from IE, Excel says it can't open the file because it's corrupt. If they save and open, Excel offers to repair the file. From each sheet in the file, it says "Removed Feature: View from /xl/worksheets/sheet1.xml part". I tried upgrading to 3.11 and the results were the same.
I haven't been able to find anything through Google, and I have Excel 2010 and can't reproduce the problem. Has anyone else had a similar issue? Thanks very much Jon Renaut
