A few bugs

Hi there.

When I try to insert an un breakable space in the automatic replacement list, it does not work, it is recorded as a simple space

When I use multiple selection view, the ends of all the lines are truncated

When I use multiple selection view with a fairly long document and I scroll to the end, the cursor has inpredcitible behaviour, not staying where i clic, and if i scroll back up, the view is allways scrolling back to the end when I clic in the window to place my cursor.
