I'm having a very strange issue with IE9. I've developed a portlet in Liferay that captures some data a uses it to print a graph with jqplot. Everything works perfectly in any browser except for IE9. The curious thing is that it occures when the explorer is opened and until I click F12 to show the "developer tools". Without any changes and reloading the page everything starts working and the graph is showed all the times until I closed the explorer. As a summary, I put a graph in a page and it's not showned in IE9 until I open the developer tools. ¿?.
Thanks for any help you can give me.
