IE8 on Windows 7 Pro 32bit:
Known issue that clicking on a link in a web page designated “target=_blank” fails to open as well as right click and “Open in new window” fails. I have read more posts than I can count on this subject but folks always seem to get an answer that is irrelevant to the issue.
Also found that after installing IE8 on Win XP SP2 and SP3 SolidWorks will no longer function unless logged in as Admin.
