Also, Kumasasa, I reinstalled as you suggested and the problem ceased to occur. Sorry for not telling you guys sooner.

Also, when I clicked Attach A Screenshot, it just redirected me to:
http://www.oracle.com/technetwork/java/index.html
Any ideas?

Kumasasa, I checked that. uninstalled Java 6 updates 22 and 25, and Java 7 update 6. should I uninstall Java 7 update 10 and reinstall it?
