I already read this thread and used the attached *.css file to try and fix the problem. I am, however, using views in the layout in my current project which [i]may[/] affect this.
I have 2 cells, with cell B having two views. Cell A has a grid attached to it. Cell B has an empty default view and an view containing a tabbar. All native DHTMLX components. When switching to the default empty view “def”, the progress indicator works. When switching to the tabbar view, the whole tabbar area cuts off the progress indicator. You can, however, see the header and toolbar change colour which means it’s probably an z-index problem.
