I think I now hold the record for looking in the wrong place the whole time. I've found what's wrong with my use of DisplayToastW.
I separated out the code in MPPluginHeader.h among my own header files for more logical organisation of the code. Initially, I wasn't worrying about Unicode, but then switched to it.

Turns out the lParam of 'MessengerPlus_DisplayToast' is FALSE for ANSI, TRUE for Unicode.
