Corel Draw X5 close button missing in action

Hi Laserists

My Corel X5 running on XP, the file close button [x] on the window that lives below the Corel close [x] button is not there. Any help it getting it back would be good, I tried the repair option and that didn't help. Any ideas? It does the same function as control f4. I don't really want to uninstall as I may need to re-license it.

Btw. I laser cut some stainless on my 60watt ULS today. The 0.05mm cut ok with minor warping. The 0.1mm took 5 passes and warped like crazy. I am going to try chemical etching next (0.3mm stainless steel) and lasering off a spray paint resist, should be fun.

Cheers
Keith

More information. I tried clicking where the [x] button should be and it works! So its just not drawing it. I wonder if its because I have XP in classic mode?
