Knife Tool: Why does it keep de-selecting my mesh?

Hi Blender fans,

I apologise if this isn’t in the right place, and if it’s such a ridiculously noobish question to ask, but I am tearing my hair out with this.

I fully understand what the knife tool is, does, and how it works. What I don’t understand, and can’t seem to mitigate, is why it de-selects the mesh / vertices / faces etc I have currently selected, every time I use it!

I’ve googled, searched, and looked through many forum posts about this. I would really appreciate it if someone could give me a solution. I don’t really want to keep having to hit A twice EVERY time I want to re-select the mesh to cut!



Anyone? I’d really appreciate an answer to this. :frowning:
