Problem
On some ie7 on Vista the browser "bugs out" and stop rendering, when we "view source" we can't see the bottom half of the html, it always is cut at the same place - where the FlyTreView html code are... This problem only occur on some clients, and it only began like 2 weeks ago, so we suspect that some hotfix from microsoft is the culprit.
On firefox and windows xp/ie7 we can't recreate the problem. We know that FlytreeView are involved, because if you choose to display data in a list on this page, the page is rendered correctly, and the html is always cut in Flytree html. This happens also only when logging in first time, if one refesh the page, the page is rendered correctly. I have tried your last version of the control, and get the same problem.
I send you the html that is rendered, both when it succeed and fail, I will also send you the .net code.
