CorelDraw : How to export very large image files?

Is there any way for CorelDraw X6 to export very large TIFF files? e.g. greater than 30,000 pixels in each dimension? I am currently running X5 on XP 32-bit and it cannot seem to handle it, even though Photo-Paint appears to have the ability.

I finally manage to get our IT guys to give me a Win7 64-bit test machine for me to trial X6 64-bit, but seems to only do marginally better than my X5 installation. The test machine already has 7GB RAM installed plus a very, very large drive.

I also had to run the same test on Adobe Illustrator and it was able to deal with this very quickly and smoothly, no troubles at all.

You may find it hard to believe, but I actually like using CorelDraw :-), which is so far the standard package for our company, but if I cannot get X6 doing what we want, I'm afraid it's the end of the line.
