OK, so I’m a cheapskate.  I still use CorelDraw 7 even though they’re up to X3 (or is that down to X3?) now.

 I found that when I opened a directory with a .CPT file in it, Windows Explorer would close spontaneously.  Fellow workers said it’s something to do with the automatic icon-making function in PhotoPaint and they were right.

 To fix it, go to CORELDraw7 | Graphics Utilities | Uninstall Thumbnail display.

 Job done.

If you use SlickRun and you can see it running in Task Manager but not on your screen, check if it’s running on a display your computer thinks you have, but isn’t really there.

Right-click desktop | Settings | Advanced | click on your graphics adapter’s tab and see if the display is set to dual view.  Worked for me on an nVidia display.
