I just installed ST2 on a dual monitor Windows 8 machine (64 bit). If ST2 is on monitor #2, the main menus actually appear on monitor #1. When ST2 is on monitor #1, there’s no problem. Monitor ordering is #2 on the left, #1 on the right with 2 marked as Primary.
Anyone else seeing this? I quickly tried the latest ST3 Beta and it’s exhibiting the same behavior.
