"accept changes" get stuck

[ranshalit]

Hello,

I have issues when choosing "I will configure partitions" on install of centOS 7.
I do it in a virtual machine (virtualbox).
After I configure partitions, and click done, I get the "accept changes" or "cancel", but nothing happens on clicking accept changes.

Thanks for any idea,

It's a bug in the kernel that does this only with vbox. You'll have to use the tab key to change the focus to the button you want to select (it'll be outlined with a faint dotted line when it has the focus) and then press the spacebar to press the button.
