Hello,
I would like ask you, if you have the same problem with preformatted text on KT 5.1.0. It was OK on version 5.0.1 or 5.0.4. I created own book from html, but on KT it looks differently, than on older firmwares. Especially I have problem with <CODE> tag and <PRE> tag. In last version it certainly show the text between CODE and PRE tags with Courier font style (fixed width, like typewriter). I tried CSS or STYLE change of font, but nothing happened, font is not still with fixed width.
Does anybody have the same problem or any solution ?
Tag <mbp:nu> stops working too with firmware update to 5.1.0

Thank you for any idea, how to solve this.
