Dear Dalyoung,

I can confirm that there is still a serious issue with the way mkiv handles the bounds of integral signs, and this has been reported several times by Aditya, myself and others.
In particular the latest beta (version 2012.11.06 09:56) handles the bounds somwhat inconsistently, depending on the fonts used:
	• with the default LM fonts, the bounds of the integral sign are correct in displayed maths, but are too close whith inline maths;
	• with the default xits fonts, the bounds of the integral sign are too far away in displayed maths, but are a little bit far whith inline maths.

Here are the source file for my testing and the resulting PDF file. PLease typeset the file both with mkii and mkiv to see the differences.
Hans did some changes recently, which resulted in a better behaviour of the bug, but still the problem is not completely solved.

Best regards: OK
