Switching between Reading and Live/Source views using OPT+L does not work (have checked that the hot key is set). I can only change to the editing modes from the buttons on the interface. Furthermore, when in those modes, the screen for editing is truncated to just a few lines in the editing window, right at the top and below the title. At first I thought that I was not getting the window at all.
changed vaults. Other vaults seem to work ok - so I have no idea what is happening with this particular vault, which is my main work vault.
changed themes to no effect
Right now, I am not able to create any notes at all as the available window for working in is totally unusable!
