Bug 40933 – Playing movie full screen on second monitor hides menu bar and title bar on main monitor

• Component: Media
• Status: RESOLVED FIXED

[Jer Noble]

Click the 'expand' button in the lower right, while window is on second monitor. The movie expands to fill the screen, but the dock and title bar on the main monitor hide themselves for no reason.

You have some extra trailing spaces on this line of code.

This comment says > 10.6, but the code says >= 10.6.

I don't think you need those parentheses.

I recommend using a "return" here to avoid the need for the else and the ugly need to have code outside the #if indented based on code inside the #if.

Is the respondsToSelector: call needed or helpful?

Drat.  Will remove.

I'll update the comment to match the code.

That's a good idea.  I've seen the "else on the other side of a #endif" idiom used elsewhere, but the early return works much better.

Only if this code is built on Snow Leopard but run on Leopard.  

Thanks!
