The UM Page it don't work in IE9 browser,but i use the Firefox/Chrome browser,The Login's Page it can be displayed properly.

IE6~8 i have not tested.what's going on？

it works fine for me. are you sure you use v5.6 ?

The first i used v5.4 to test,it don’t work,so i upgrade to v5.6,but it also don't work
I had tested two pc with IE9 browser,the problem is still there

This problem was fixed in v5.6. We just tested on two PCs and there is no problem. Make sure you have applied the latest Windows updates, maybe your IE9 has a problem.

i just tested the third pc with IE9,the problem are still there
but when i change the os to XP or 2K3 with IE6,it's work normal,IE7~8 i have not test
Is a serious problem that we can't use IE9 to Login UM
