Hi dhtmlx support,
I’m having another problem with your: custom dhtmlxwindows.js you gave me on: dhtmlx.com/docs/products/kb/inde … 762&a=3766)
Regards
With such initialization, window will use all body as content area. It possible that in case of your HTML layout body has height lesser than window height ( if your HTML layout based on absolutly positioned containers, the height of body in FF can be equal to 0 ) - in such case window may try to adjust position, which can cause similar effect.
Please try to add next rules to your css file.
html, body {
height:100%;
}
