Wow... old version?

I'm using the PocketPuTTY 2007-02-28 dev build for WM2003 (release) version, its really good!
Ah... and the | key works fine in that version.
I used to be able to use the red dot + sym (spacebar) + \ to get the | symbol as well, but that seems to not be working anymore for me... must have forgot the mojo for that
Yep, that does not work (on screen keyboard does, but you should be able to type \ then red-dot, then space, to get |, repeat to get /)
