OT: strange VidCVap (or not) behaviour

Maybe it's the computer?
In preparation for recording a concert next week, I was making minor adjustments to one of my Vegas suites at work.
I ran tone from the audio board and colour bars from the switcher to a Vegas suite.
When the lines get to the room, they go into a JVC miniDV deck and then firewire into Vegas .
It's a dual monitor setup.
I fired up VidCap, hit record and then moved the capture window back and forth across the two monitors a few times.
Why I have no idea but I was just playing around.
As I was doing this, I noticed that the audio would drop out right at the point where VidCap crossed from monitor A to monitor B.
When I ended the capture, I noticed that several clips had been created instead of the one I expected.
Sure enough, each time the VidCap screen moved from one monitor to the other, it treated it as a scene break and started a new clip.
Edit suite #1 has a Dell quad core with Vegas 8.
Edit suite #2 has an IBM Intellistation with Vegas 7.
My original suspicion was the video card driver but it did this on both edit suites so now I'm not sure.
Has anyone ever seen this before?

BTW, I tried doing this (moving VidCap) while I was capturing a tape that had no timecode breaks and it did it to this capture as well :-(

Maybe as it crossed from one monitor to the other the CPU load caused VidCap to loose the plot for a moment and the break in the stream had to be resolved by creating a new clip.

I thought of that too Bob but, on Task Manager, it goes from 3% to 6% and back to 3% again.
Surely that wouldn't do it - or would it?

Task manager can only only "see" so much by my understanding.
VidCap seems to cope very well with loosing focus, I cause that to happen quite a lot with no drama. Maybe the window switching causes it to not loose focus but something else interrupts it causing to to think it's lost the data stream from the VCR.
VidCap can cope with broken TC, I *think* it has issues though with breaks in the data stream that could signal TC resets etc.
