MUSHclient 1.03 release notes
Version 1.03
1. Fixed the handling of selecting text in the output window, when using a proportionally-spaced font. Previous versions would not have selected text accurately if a proportionally-spaced font was chosen.
2. Improved the selecting of characters in the output window, when clicking with the mouse. Previously you had to click at the very left of a character to start a selection. Now you can click up to about half-way through the letter and still select it.
3. Added the capability to extend a selection in the output window by shift-clicking.
