my charts seem to repaint themselves over all other html, including pop up dialogs. the problem is particularly apparent in IE7, making our app nearly unusable. suggestions would be greatly appreciated.
here is a summary of where I've noticed the problem:
windows server 2003, Firefox 2.0, bad
windows server 2003, IE&, very bad, app is unusable
OS-X, Firefox 2.0, no problems at all
OX-X, Safari 3.0, no problems at all
also, the app is built in Ext.js 2.0.
