I have searched all my C-drive and I have not found vptray.exe.
Enter on "groups" page of Google.com and make a search.
There are a lot of topics about it and maybe they can help you to solve the problem.
It seems to be a virus scanner, and this can explain its strange behavior. :)

Good luck!

So, reformulating:

There is running on your computer a virus scanner program?
Somehow Norton Antivirus?

Close it.
If it's a service, stop it from Control Panel.

Then see if your problem occurs again.
Eventually, if it's a virus scanner's fault, report this to the manufacturer.

Possible, your application keeps opened some file in an exclusive sharing mode.
That does not allow another application to open the file even for reading.
If the other application deos not catch this exception, very possible it fails.

One of my colleagues, writting a communication module, needed a thread timer to check something.
He used something like ::SetTimer(NULL, 0, 10000, NULL).
In OnTimer handler, given some condition and for some reason, he set the thread timer again, but forgot to kill the old timer before.
The bug did occur at one client who forgot the application running over the night :D :D (the application froze).

So if you find this, just keep in a member variable the value returned by SetTimer and use it for KillTimer before setting the timer again.
