Problems with Internet Explorer

Hello, I posted a topic some days ago, but I still got no answer.

When I use weather watcher, (and I use it for a long time now) I regularly get a message, that Internet explorer caused an error. I tested it for a couple of days.
When I do not load weather watcher, I do not get this error at all.
These problems started since I updated from the windows update site, about 2 weeks ago.

As soon as I start weather watcher, the problems arise again.
I freshly installed windows Xp a couple of times, and installed all the programs I normally use, but the problems with Internet Explorer only arise, as soon as I install and use Weather Watcher.

Please, tell me, is there something I can do, so that the program works without these problems.
