Popup error when layout with grid resized: 'style' is empty

Suite and Optimus Suite 5
#1

Hi I have a page with layout and grid inside.
When I click on the border of layout between grid and paging info a pop-up shows up at the top-left corner of browser (IE and Firefox only) with text:

Javascript ErrorThe next error ocured :
'style' is empty or is not an object in http://server/dhtmlx/dhtmlxLayout/codebase/dhtmlxcontainer.js at line 21
If you think that error can be caused by dhtmlxtree press the 'Generate report' button and send generated report to support@dhtmlx.com

Everything works perfect, so I would like this message not to show up.
What couses the problem? How can I suppress this message?
PHP generated body below:

[code]

TITLE
[/code]

Any chance for a tip from support team?
