dhtmlxtabbar on secure site with https

I get IE Security Information alert box (“This page contains both secure and non secure items. Do you want to display the non secure item?”) when using dhtmlxtabbar on a secure website using iframes.



I checked the images etc. and they all have urls as https. Works fine with firefox.



In case of IE, if I say to show only secure, the website still works fine.



Any idea what is wrong?

If you using iframe based loading mode - please be sure that you have blank.html in tabbar image directory. ( this image used as temp spacer for iframes, because empty iframe url will generate mentioned message in IE )
If you are using old version of tabbar - please try to use latest files from dhmlx.com ( the last similar problem was fixed few moths ago, so it will help only if you version of tabbar is pretty old )

Unfortunately problem can’t be reconstructed with local samples. If problem still occurs for you - please provide any kind of sample where problem can be reconstructed. ( you can send it directly to support@dhtmlx.com )
