All of a sudden, this morning I started getting this type of message whenever I try to click on a link or open a new tab: "C:\PROGRA~2/Java\jreg6\bin\ssvagent.exe Overlapped I/O operation is in progress." Since I am not a computer specialist, but only a regular user, I am asking for a little bit of help on the part of those who know what this message is about and what I should do to get things fixed. My operating system is Vista Home Premium 64, Service Pack 1, and the Internet browser is Windows Internet Explorer 7. Thank you.
