Hi all,

I've come across a strange bug in Excel. When I insert a pie chart or doughnut chart, it no longer appear as a round shape (see image). It doesn't seem to be a chart template issue as all the default templates (except one) all show the same problem. The only one that doesn't uses a 3D effect, and curiously I have found that if I add a 3D effect to a pie chart it resolves the problem.

I've tried using completely new spreadsheets too, so it doesn't seem to be a corruption in the file.

Has anyone else experienced this issue or know how to fix? I have run a repair of my office installation, checked for updates, and rebooted and still it is not resolved.
