Parallels 7 Windows7 CorelDraw x5 issue - edit bitmap does not open Photo Paint

Hi

I am an I.T. teacher using CorelDraw 5 with Parallels 7 on a MacBookPro to access Windows 7 and CorelDraw X5 -

Nornally CorelDraw x5 will launch Photo Paint when you choose Edit Bitmap from Corel Draw. Then you can edit in photo paint and on save and close you are back in Corel Draw and able to continue there. However this is not the case for me with Parallels 7. It does not launch Photo Paint as expected. Does anyone know why and have a fix for this. I would appreciate it if you could help.

Thanks
Gerald
