Excel application - can't remove from memory

[dre99gsx]

I'm opening and reading a worksheet using the Excel application/reference methods from Labview.  Worked fine until some short time ago where now all my sheets are opened up as "read-only".  Worse yet, when I try to close the sheet and Quit excel application, task mgr shows it is still resident in memory.

This worked well until our IT department added some Microsoft updates.  Any ideas?

I'm guessing the microsoft updates have somehow set the files to be read only now. I'd find the files on your disk and check their properties. As for it being resident in memory, is the reference still open? I'm not sure if this would cause this issue, but it may. Make sure you close any references relating to your file when you are done with them, then close the file.
