Description of Problem:
"Next" button doesn't work after fdisk,
until one moves the cursor off of the "Next" button, then back on.
How Reproducible: Consistent
Steps to Reproduce:
1. GUI install, use fdisk to partition
2. While actually in fdisk,
leave mouse over greyed out "Next" button.
3. Write the partition table, leaving mouse over "Next" button.
4. When screen shows "Select drive to run fdisk on" again,
clicking the mouse button on the "Next" button that it is still over,
just boldens the button's border, without advancing to the next screen.
5. Move the mouse off of the button, then back on for button to work.
Actual Results: Clicking "Next" button doesn't advance to next screen
if mouse has been left over "Next" button.
Expected Results: Clicking "Next" button advances to next screen
without having to move mouse off of button,
then back on.
I have reproduced this problem.
It's weird, though, because we are re-enabling the "Next" button, but it's not
grabbing the focus.
I think this is more of a GTK problem with grabbing the focus when the child
window is destroyed. This problem only happens if the mouse is over the button
when you exit fdisk. As such, I think this is pretty uncommon and isn't worth
fixing, given the number of other issues that we're looking at.
