I am a very casual user but loyal since Corel draw 2.0 many years ago.
I am running X3 Version 13.0.0.739 ...
In the past (older versions), when I wanted to create a label I went to the page setup, choose the Avery style and started drawing. Printing out was more or less automatically and I ended up with nice labels, formated right onto the Avery sheets.
For the very first time I am trying the same thing in X3 using the AVERY 5371 under labels in Page Setup:
Everything fine so far, the screen shows the correct size and I am designing. When I am trying to create a second page (label or businesscard) the screen goes back to letter size and I can't run page setup again to put it in label mode again (greyed out).
Whether I have only one page (label) or more in the document, when I am trying to output, everything falls back into letter size and my label is nicely centered on that page.
What am I missing here or is X3 having a bug with page setup ...?
I tried to get help from Corel but the want $25 just to talk to me 
Did somebody had the same issue or can somebody help me to to do the page setup right? I tried Help and the Manual and did as stated there but it doesn't work....
Thanks for any help
