I am using their latest verision - Webresearch 3 Professional. I had written to macropool and received a prompt reply with some suggestions which i have done. In the entire history of this product they had about 10 reports of this issue.
In 80% of the cases reported, a defective Internet Explorer was cause of the problem. In 20%, a security software blocked access to the Internet Explorer interfaces. They feel that this could be a cause. One additional cause they say could be that my computer is spyware infected
I am still on IE 7.
