I'm using the align tools to align the corner of my dataframes and labels.
I first snap my dataframes to my guides and then align the labels to the top-right corner.
As you can see on the attachment, the dataframe isn't right on the guide even though it is snaped to it. when I align the label to the corner of the dataframe, it is right on the guide (but wasn't snaped to it) which tells me there's something wrong with my dataframes.
I have other graphic items in my map and the snap works fine. It's only a problem that occurs from time to time... I've made 4 other maps like this one and everything was fine and they were all made from the same original document...
Any idea why?
