This a bit odd. You'll notice that whenever you hit enter by itself on the spellcheck window it will close the window. However, the close button is always show as being active. You'll notice when you tab a small highlight is applied to the button. You can select this button by using space. So in your case, pressing tab, space would change the word, instead of closing the window.
I'm unsure if this is intended or not however; it's also unclear if this is a gtk issue or something specific to abiword ** Changed in: abiword (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1160976 Title: the Spelling window closes without changing the words when use Tab button To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/abiword/+bug/1160976/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
