Hidden Adventure

Can someone help please.
I started an adventure yesterday, but no 'Adventure Window' opened, so cannot visit, send army or cancel. Any hints would be helpful>

Look in your quest scroll.

Thank you, did find it in there, but could only cancel it. Ah well :(

if you click the little box next to the adv quest in questbook, it brings up the box on right of screen

It didn't for me, just the 'cancel' option, thanks for all the advice though :)
