I'm evaluating Tree Menu and have problems with IE7.
Firefox 126.96.36.199 works fine.
When I expand and collapse a submenu it works but when I click on any links in the submenu the menu collapses for up to 20 seconds and then auto expand.
Sometimes it seems to work but then if I click the same link a couple of times it starts to collapse the parent submenu again. It seems totally random on which link it starts to behave strange.
The site is in swedish but you can check it in IE7. It's the "Aktiviteter" link.
