I was drive crazy by Gimp this morning because of this. The move tool has a mode: move layers&#x2F;guides, move the selection or move a path. Sometimes, somehow the mode flips to &quot;selection&quot; and stays there, leaving the user unable to pick and move a guide line (even if the user clicks on the ruler first, which is usually the trick to get into a mode where you can pick a guide line). Just figuring out why it stopped working had me baffled; at one point I &quot;fixed&quot; it by quitting and restarting Gimp thinking it was a bug. Then I found the answer online. Grrr! Though I know what to do, it&#x27;s still annoying to have to bring up the tool options dialog on the move tool whenever I can&#x27;t move a guide.
