CorelDRAW Graphics Suite X5 :: Cannot Access File Because It Is Being Used By Another Process

Corel X4 and all other versions before, Autocad & 3DS Max, create nifty graphic in Corel, export as image (jpeg 90% of time), Hit render in Acad & 3ds, tweek graphic in Corel - export again, hit render again, over and over and over until result is satifactory.

Corel X5, same process UNTIL I render once in Acad or 3ds, then try to export same jpeg from Corel then bam, "Cannot access file because it is being used by another process", this has to be a joke, right ? I have to shut down Acad AND OR 3ds then export out of Corel, then launch and reopen Acad & or 3ds file.

This is what I do at work all day long, I currently have reinstalled Corel X4 just so I can continue to work.The exported file is not being edited or used at the time I export form Corel, Coreldraw THINKS it is being used. The file is only being used during the time it takes to be rendered, I have been doing this for years and have never got a file locked message before.

Things I have tried to remedy this.

1. Look at the security properties of the actual exported image file, everything is set to full control for everyone & I dont see anything about file locking.

2. Scanned the "options" & "customization" section in Coreldraw, I cannot see anything that would control a setting like this.

3. Unchecked all options in jpeg export dialogue except anti-alias, I knew this had nothing to do with it but you leave nothing left to chance.

I cannot think of any program that a typical user may have on their Windows machine to test this out, I know when you open an image in an editor like MS Paint, you of course cannot overwrite the image file from another program, that is what Coreldraw X5 believes is the situation, but it is not.

export a jpeg from Corel X5, click on the jpeg and it will open in Windows Photo Viewer, keep it open in the viewer then change the graphic in Corel, export it again to the same file name, it will ask if you want to overwrite it, say yes, it WILL NOT say that the file is in use, export it, then close the Windows viewer, open the same file in the viewer, it has not changed from the original export, THAT is crazy beyond words, I have never seen a process on a computer being completed with no error message while  the process was never actually done, that goes beyond the current intelligence of computers, and I believe this is the crux of the problem.
