I've done some experimenting with this, and have found out that if I change the module style to "none" then the extra space on the right goes away. Howerver, I would prefer the "white space " to be there, just equal.
I changed to the light style also, and can see that the missing black border at the top and bottom is actually there, it's just that it is white instead of black, but in ie10 it shows up as black. It is white on Firefox, ie11, and safari.
Any chance of someone taking a look? http://henkestrand.com
