Problems with progress bar on IE
We're using your component to create a naviagation menu that is included in every page on our site. The menu spans several sublevels and we found a problem:
When we click one of the links in a sub-menu that references a slow loading page, and we move the mouse out of the menu, IE shows the progress bar running and completing. However, the page itself hasn't loaded yet...and it can go up to several seconds until the page finally shows up while the user is kept in the dark regarding progress.
This is causing usability problems because sometimes the users assume that the link is simply not doing anything.
If we keep the mouse pointer on top of the link then the progress bar works correctly and only gets to 100% when the page actually appears.
I know you are not responsible for maintaining the progress bar (that's stricktly IE) but I have a feeling that this behaviour is caused by the events fired on mouseout or similar.
Have you seen this problem and do you have any information on how to workaround it?
