Hi Ypnos, darn, I had thought this was solved in the just released Jul-25 version...

Please make sure you are running that newest version and not the Jul-17 one.

About IE7 - MoI uses the display engine of IE for showing its own user interface. So that's why if something is not working right with IE it can mess up MoI.

A couple of things you can try - there is a Reset button in IE7 under Tools / Internet Options / Advanced tab, it is a "Reset" button on the bottom of that dialog. If you can try pushing that it will restore default settings which help.

Also if something has gotten messed up in the system registry for the Windows scriping engine stuff it can also cause problems. You can reset the registry for these items by following these instructions:
