I'm unable to close Rebase dialog box after performing Rebase command. There are two buttons: Continue and Abort - clicking both buttons will cause brief change of status text from "You may continue the rebase" to "Running...". The only way how to close this dialog box is using Escape with following confirmation: "Confirm Exit / Exiting with an unfinished rebase is not recommended. / Consider aborting the rebase first / Exit / Cancel"
I can reproduce this problem on our repository, unfortunately it is private source code.
