Affects Version/s: Minecraft 1.4.5, Minecraft 1.4.6
Fix Version/s: None
Environment:Dual-Screen, MacBook Pro, Mac OS X Lion 10.7.5, Java 1.6.0_37
Started minecraft launcher, and moved it onto my macbook display (screen two), before starting minecraft. This is the first time I've used mc on my built in display.
I had Parallels running in the background with Windows 8 running with Coherence mode on and with Xara Designer Pro. I had firefox running in OS X with a dynmap on screen.
I hit t and minecraft crashes
I do get error reports. The first two reports (crash-2012-12-22_16.45.06-client.txt and crash-2012-12-22_16.46.48-client.txt) are for 1.4.5, and crash-2012-12-22_17.02.17-client.txt is for 1.4.6
Minecraft crashes regardless of whether I am in Creative Singleplayer or Creative Multiplayer. I have not tried SMP or SSP.
Hope this helps!
P.S: I could not find this bug already reported. If it has already been reported, let me know!
