An early warning about the above patch which makes the dictionary pop-up widget bigger.
Some of the nickel code we have been using to achieve the size increase has been removed in 4.10.11591. I have only had a quick look at the new nickel code but it is not immediately obvious to me how to reproduce the old effects.
Consequently, you will need to disable this patch until further notice.
I will keep looking for a new solution over the next few days, but no guarantees. If anyone has any bright ideas don't hesitate to PM me
Update:
I've had another look and still cannot see any way to define a custom dictionary pop-up frame size. However parts of the old patch can be salvaged to reduce some of the excess whitespace used (header, footer, margins) and this will result in an increased text area available for the actual dictionary definitions.
I have sent a proposed replacement patch to geek1011 for inclusion in the standard pack.
Please note the new patch name has been changed to Dictionary pop-up - increase available text area so as not to be misleading.
