Left-handed mouse patch
Our software is built on the MonoGame framework, which doesn't natively support left-handed mice. Therefore, our software doesn't support left-handed mice out of the box. However, as discussed in this thread, Rayco from our forum patched the MonoGame dll to work for left-handed mice. You can download the resulting dll here, copy it over the existing dll inside the folder containing the SmartScope executable and you should be fine.
Note: in case this doesn't work, let us know in the forum as we might need to update the dll once in a while.
