New browser is sent to background instead of foreground where it is expected (should be top of z-order). This is not the same behavior as seen with earlier versions.
Tested with expected results using the following JRE versions in Internet Explorer 7 on Windows XP SP3:
Sun JRE 1.3.1_21
Sun JRE 1.5.0_16
Sun JRE 1.6.0_07
Fails when using JRE/JPI build 1.6.0_10-b33.
