Can't set corect page size. On CorelDRAW X4,
If I add for example 15 cm page size. Corel Draw automaticaly fix that to 150 cm.
Below I added the image with explanation.Maybe someone had same problem? :)
I would check Drawing Scale
Tools – Options – Document – Guidelines – Rules – Edit Scale
As far I can see, it's a problem with decimal separator. You are not using decimals fractions, I'm not sure if it's something relative to your local Windows settings (according your region it could be a dot or a comma)
