Proxomitron parsing results in "File Access Removed!"

[febber]

I'm using proxomitron version 4.5.0.4.

This program gets confused and issues a warning of
"File Access Removed!" when there is no exploit.

Here is one example:

Look at entry 71

With prox bypass off:

Thanks File Access Removed!

With prox bypass on:

Thanks

The source is an IPTV recording with an overall bitrate of 8500 Kbps and resolution of 720 x 576.

This is the avs script:
SetMTMode(5,2)
MPEG2Source("D:\test.d2v")
SetMTMode(2)
LeakKernelDeint(order=1,threshold=8)
Crop(2,2,-2,-2)
BicubicResize(672,368,0,0.5)
Trim(17518,56467)

The specs of the system:
i7 930 @ 3520Mhz
3GB DDR3 RAM
2x 250GB WD RAID0
Windows XP SP3.

If have also an i7 980x @ 3750Mhz, wonder what that will do

So, what causes the "File Access Removed!"?

Can this be fixed?
