I cannot use the scrolls of Awaken.
I read the post about dead bodies disappearing but i still cannot use the scrolls.
I try to pause the game but when I right click the scroll my character just picks it up as they would with a right click.
Any advice on this issue ?

I had a problem as did many others using scrolls too. There's a trick to it. But the bad news is, having not played the game in a few years, I don't remember what it is. However, I'm sure it was covered in past threads. So, unfortunately, my advise is that, if nobody has the answer here, to go the painful and tedious research the old posts route.

OK , so I figured it out by trial and very annoyed error.
Right click scroll of awaken in Inventory then right click character portrait and your currently selected character will find the body.
Don't try to cast on ground or you may resurrect an enemy and waste a scroll - happened more than i would like to admit.

Glad that you got it to work; sad that it was so much trouble. There just aren't enough people viewing this to have a lot of quick, good answers.
