Run MCC_Sandbox with CBA.

FIGURED IT OUT FINALLY!! It was the keybindings. For some reason the last game patch must have changed how the game handles key binds. The profile I was loading in with had several rebound keys. Switching to default binds fixed the problem completely. It should be noted that this exact profile and mods were in use with ACE prior to and following the release of the hotfix for 1.64. In order to begin work on a new public server mission I loaded the game without ACE and discovered the bug. ACE's keybind structure must effect the key in question and thus the reason it works with ACE. I will continue to test this week for a definitive answer as to exactly which key is causing the problem.
