[bug] controls stop when accessing throne room's obtain 10 gems

[Hervé Simard]

Just started a new game and made the firsts quests.
Got quest to customize my throne room, but when I click on the "Obtain 10 gems" button, the controls switch to the navigator, which means that I cannot continue. This happens each time I try and click this button.

I will add as a support that I'm using Internet Explorer 9 on a vista up-to-date laptop. If you need any other information, just ask.
