Problem with war page

I was wondering if anyone else had this issue: When I go to the war page and try to move units around by clicking on them (or in fact try to do anything at all like opening the menu for attacking a city or a corporation) the map just freezes and the webpage does not respond for about a minute or so. Then it starts again moving for only a few seconds and then again it freezes for a minute and so on. I'm having this issue in my home computer where I have wondows 7 with Explorer, while in my office computer (he he) I never had this issue (windows XP with Firefox). This way, raiding a C3 lasts 7 minutes in my office computer and about 90 minutes at home! lol

Does anyone have a clue?
P.S. Also, units do not move around properly-instead they're all over the place, except when you set them at a specific target (city, town, corp etc).

Are both computers using the same version of Firefox? Please try upgrading the Firefox on your home computer.
If that does not help, please open the 'Web console' from the Tools/Web Developer menu.
Are there strange errors on the console?

Units moving to wrong map locations is caused by zooming the page with the browser. Please return to the default page size (CTRL+0) for the war page.

Thanks for the reply, I'll try it out.
