Different window resolutions, it turns out, did not work with the method I used to place the text. If this was what caused your issue, it should be fixed in the updated version in the original post. It has been tested locally using 1366x768, 1360x768, 1280x768, 1280x720 and 1024x720. My first thought is that this could be caused by a conflict between Editor Tools and a previous version (since the previous mod's dll was named EdTools, simply copying the dll for the updated plugin, EditorTools, would not overwrite the older version). Can you confirm that there is no EdTools.dll in your Plugins folder? I've added additional information in the original post. Thank you. Sorry for the issues you're experiencing. I've made a further update that may resolve the symmetry circle issues (see above for reason, if you're interested). For the 'double text', my first thought, as stated above, is that this could be caused by a conflict between Editor Tools and a previous version (since the previous mod's dll was named EdTools, simply copying the dll for the updated plugin, EditorTools, would not overwrite the older version). Can you confirm that there is no EdTools.dll in your Plugins folder? For vertical snap to work, you must also have angle snap enabled as far as I can tell. If vertical snap is nonfunctional and you have confirmed that angle snap is enabled, then please let me know.
