random crashes upon start-up

Hello:

From time to time, rarely, I get the odd crash upon launching pl/sql developer. This morning it displayed quite a few message boxes: "Privileged instruction". Only one was visible and another one popped-up as soon as closed the previous one. After I closed all of them the toolbars were empty. I closed pl/sql developer, restarted it and everything was fine.

Has anyone else seen this? This is not the first time it happened - different errors though - but it happened rarely enough to not be concerned.

Here is the call stack info:

I'm not sure what could cause this. The stack dump does not contain any useful clues either. Can you try this on s different PC to check if the error is caused by something in the environment?
 
It is hard to reproduce this because it occurs so rarely. I will keep an eye on it for now. Since I posted the message there have been no crashes.

I don't normally run anti-virus software but I did a virus scan with Norton and Kaspersky. I was worried that perhaps I caught something but I didn't find anything.
