I ran into a very strange situation where my flex2 (beta2 and
beta3) application is big enough to cause browser scrollbars to
appear. In such a case, if I scroll the browser, then all button
controls in the flex2 app can not listen to mouse events any more.
I found this problem with Firefox (v1.5) in Windows XP. IE in XP is
perfectly fine. Below is the code, simple enough to illustrate my
situation. To test, please compile the first file into test.swf,
and then access test.html form Firefox. Thanks.
