CorelDRAW X6 :: Exporting Selected Only Artwork To EPS

Program: CorelDraw X6 64 bitOS: Windows 7 SP1 64 bit

I have problem when exporting selected only artwork to eps. The artwork itself contains standard fill objects with no strokes and no special effect on each object (drop shadow, powerclip, etc). On EPS Export dialog I change nothing, just clicked OK button.

The problem is there is no sign if the process success or fail.The file created only have zero bytes.The File>Exit menu is dimmed.When I try to close the document, it say:

Some of the documents could not be closed, because tasks are being performed in the background. Check the status bar of each opened document to see what tasks are being performed and their progress.

I can't close the document and exit the program, so I have to use Task Manager. Also if I continue to edit the artwork, i.e. selecting an object inside a group, the program crashed.
