On windows, when you select a line or a word, the drag&drop text functionality is active even if you do a single click, so you don't loose the current selection like it should. I can still click somewhere else on the text, but if i've selected the whole document, i don't have any other solution than doing a copy/pastle to remove the selection. Clicking on the selection or outside on the whitespace doesn't help.
Doing a double-click work however, it select the first group of characters like it should.
It may be hard to reproduce, because even on my computer, the bug doesn't always appear (but is here most of the time however)
(another problem, but maybe something harder to fix: search inside big documents (>20mb) make any operation really slow (it's slow to open the search bar, it's slow to type inside the search field, and of course it's slow to search . A search inside the same document with notepad++ work really faster for example)
EDIT: Forgot to say: Sublime Text 2, V2.01, Build 2217
