seems like a selection bug on latest beta: 20090926
try this:
- open new file
- paste this:
<bindings>
<binding key="ctrl+shift+u" command="runMacroFileSilently 'Packages/User/SwapFirstLetterCase.sublime-macro'"/>
</bindings>
now try selecting parts of the text (grab few lines), e.g. mark with mouse at <binding key="ctrl+s and start dragging the selection down, you will see the 2nd line is not displayed correctly.
vim.
