Arrow/Line behaves very strange

Hi Nick,

I expect you may have found a solution to this already, but, in case you haven't (and in case it's helpful for anyone else who happens upon this thread in the future), I wanted to chime in with a bit of follow-up help. 🙂

To find the Reset Tool option for your line tool, once you have clicked on, and selected, the line tool, over in the main toolbar on the left, do the following (The #s here are reflected in the marked-up screenshot that follows the outlined steps)*:

1.  Look up in the top-right corner of your Photoshop window, for the line tool icon, just to the right of the home/house icon, and click on the down-arrow, just to the right of the line tool icon.
   
   
2. That will pop up a small settings/selection modal window. Click on the Settings Gear icon, in the top-right corner of that little settings modal.
   
   
3. That will open up a list-based context-menu, with a bunch of different options. Click on Reset Tool in that context-menu, and you should be all set. (One thing to note, unless you're hoping to reset all of your tools, make sure to click on Reset Tool, rather than the Reset All Tools option, which is just below it!)

* Note: This is all assuming that your tools are set up as they come, by default (which, it looks like they are, in your case, Nick - but, adding this note in, for anyone else who happens upon this thread, in the future). If you've moved things around a bunch in your UI, you may need to look in slightly different places for these options, but the icons and such should all be consistent; so, just look for the relevant icons, if you're working in a customized UI.

Ok, hope this helps! LMK if any of it is unclear, or if you are up against anything else you need some help with.

Will
