Powerpoint text boxes are malfunctioning

[drnaturalist]

Upgraded to Yosemite today, and installed the last updated for Microsoft Office 2008 (oops, I know- it was published in 3/2014). Now I have several issues with powerpoint. First I cannot simply delete text boxes by selecting the entire box and hitting delete. When I do this, it now starts deleting letters and words instead of the entire box. I can no longer command + C an entire text box either, I get the angry thud sound. I can do all of these for pictures, but not for text boxes. I can no longer nudge text boxes by selecting the entire box and hitting an arrow key. It now automatically goes inside the text box. I've this version without the newest update earlier today without these issues, they only appeared after the update. Anybody have an idea what to do?
