sendandload doesn't work in IE

[ffayyca]

I have a aspx page loading a swf movie, which uses sendandload to call an external ASP script to update the database. It works in firefox but won't execute in IE. I read that the caching may be the problem, but I don't use no-cache so the XML should work. My sendandload looks like this

var _loc1 = new LoadVars();
_loc1.pos = pos_index;
if (User == undefined)
{
User = "TEST";
} // end if
_loc1.User = User;
_loc1.sendAndLoad("../wpscript.aspx", _loc2, "GET");



The script just takes the loc1 variable and queries the database. How do I fix this problem?
