Font Changed with Plesk Upgrade

[ScottT]

Hello, I have Sitebuilder 4.5 and recently upgraded from Plesk v8.6 to v9.0.1. I did not upgrade Sitebuilder with the Plesk upgrade. So, Sitebuilder should not have changed. However, customers are now reporting that websites that used the Tahoma font have mysteriously switched to the Segoe UI font within the Sitebuilder wizard. This Segoe UI font is not available from the font dropdown, nor is it visible on the published website. It is only seen within the Sitebuilder wizard. Customers are complaining that they need to change all of their website pages back to the Tahoma font. Customers who did not use the Tahoma font prior to the Plesk upgrade did not experience this problem.

Has anyone else had this font problem or know of a solution?
