I have already replied on your support ticket on the same subject, however I am pasting my reply here too:
Straight to the points from the document:
Generally speaking, the splitter is by default 300px high. If you need different height, you should set it to the Splitter's DOM element. Please have it in mind that elements with percentage height require their parent to have explicit height. If the parent also has a percentage height, the rule applies until an element with a pixel height is reached or until the <html> element is reached. This is a web standards requirement;
As for the issue 2 and issue 3 - I am not able to reproduce either of them. Could you please checkthis short screencast capture and let me know if I missed something? Also, could you specify the exact version of Kendo UI and jQuery you are using? Also, do you observe the described problems only in IE Compatibility mode? For your convenience I attached a simple HTML page which demonstrates the desired functionality.
On a side note, in the provided code snippet you have included both kendo.all.min.js andkendo.web.min.js - please note only one of them should be included at a time. For more detailed information please check the corresponding documentation.
