About KillerShell

KillerShell puts a file browser, a PowerShell or CMD terminal, a text editor and an admin toolkit in one window, on one tab strip and one set of keys. Search any folder by filename wildcard or by file content, streamed live with no index to build. Processes, services, performance and the registry are one key away. Runs portable or installs for you or every user - no runtime, no agent, no account. Open source under GPLv3.

What's new in 1.2.1

1.2.1 is a single-fix release, and an urgent one: in 1.2.0 every confirmation dialog closed the app instead of opening. Anyone on 1.2.0 should update. Fixed - Confirmation dialogs open instead of closing the app. Deleting files, replacing an entry inside an archive, ending a process and installing the portable copy all ask before they act, and in 1.2.0 the window that does the asking died the instant it was built, taking the app and the open session with it. The actions themselves were never broken - the dialog in front of them could not appear. Its caption row was sized from a theme value that held the right number in the wrong form, which a theme file can express safely and a live theme lookup cannot. It affected every theme, and it went unnoticed through 1.2.0 because it only shows when a confirmation is actually reached.
