I am afraid that the provided information is not sufficient enough in order to determine where exactly the problem comes from. Is it possible for you to provide a small but runnable jsBin
which which isolates the issue? In this way I would be able to examine your case in details and provide you with a concrete recommendations.
On a side note, could you please confirm that you are using the latest official Kendo UI release (2013.1.319 or higher). I am asking because the screen boundary detection feature of the tooltip was added in that version.
If you are using an outdated Kendo UI version, please update it and let me know if the problem still persists.
Regarding the issue which you experienced on Google Chrome, could you please test it with the Canary build
. I believe that the problem is caused by a bug in the browser which is already fixed in the latest Canary build and should be published officially soon.
