[SDL] SDL_MOUSEBUTTONDOWN being fired twice?

[L-28C]

Hello everyone!

Look at this y'all:

Isn't that bug supposed to have been fixed... 7 years ago? *Laugh*
I'm getting that error right now in my app... This event fires twice, 
but if I put a MessageBox right after the first time it only does it once...

Has anyone had this problem? Is there a workaround? Thanks!
