What I did:
1. I created a new Excel file on my desktop
2. I opened it.
3. I inserted a CommandButton into my Excel Sheet (Developer Tools | Insert | CommandButton).
4. I selected columns E to G and made them the print area (Page Layout | Print Area | Set Print Area).
What then happend:
CPU-Load rises up to 27% (I have 4 cores. If I do it on a machine with 2 cores, it rises up to 50%).
What I ask myself:
Why?
(I use Windows 7 64bit, Microsoft Excel 2010)
Try it on your Win7 64 bit with Excel 2010! What are your experiences?
