It seems right-clicks are completely nonfunctional; they no longer do anything. This seems to be true for both the Webclient and DreamSeeker.
Related to id:2034005 ?
Example code:
turf
Click(location, control, params)
params = params2list(params)
if(params["right"])
world << "Ya right clikkd" // will not display
My own tests are not showing any problems with a right-click when the menu is disabled, either; it's registering properly.
Did this work in 510.1323? And do you have a test project that shows this, because my own test project says this is working as expected.
