Ok. This never happened before. I used to be able to go to Monitor 2 to browse the web, and have the World of Minecraft Client Wrapper running in Monitor 1. Then go back to World of Minecraft and everything works.

But now, when I do that, and try to go back World of Minecraft, it hangs on me. I tell it to close, it gives me this in the Error signature;
szAppName : java.exe szAppVer : 6.0.170.4 szModName : hungapp
szModVer : 0.0.0.0 offset : 00000000

Also, in the World of Minecraft console, I see;
"ERROR: Failed to run minecraft
JAVA6="C:\Program Files\Java\jre6\bin\java.exe"
Press any key to continue . . ."

Going to the Java site, they claim I have the latest version. I installed it though an .exe I downloaded from their site. Got done with reinstalling Windows.

And I do have the latest version of the client wrapper.

EDIT: I fixed it. Reinstalled World of Minecraft and it's working as it is supposed to. :)
