the problem is that his scripts need exactly stable sws version 2.8.3..
newer betas 2.8.6 or 2.8.7 and also lower versions others then stable SWS 2.8.3 do not work...
for this scripts
some of the br_xxxx things like reaper.BR_GetMouseCursorContext()
seems to be broken within newer betas... or maybe complete missing like Breeder^^
(have looked not yet accurate...)
With SWS 2.8.3 x86 & x64 all his/this great
scripts work..
really good & much useful scripts.
but need exact sws 2.8.3
