Map screen becomes black after movement

[Pejman]

I am using IE7 and each time I drag my unit a hex for movement, the
map screen becomes black. When I change back and forth between the map
and another screen ( say rules for instance), the map is redawn
correctly and the unit has moved.

Thanks for reporting the problem.
I have now also tried to use IE7 and had the same problem. This is
most probably due to a bug in IE7. I found some info on:
http://weblogs.asp.net/rajbk/archive/2006/11/29/ie-6-7-unspecified-error-when-accessing-offsetparent-javascript.aspx
and http://groups.google.com/group/jquery-ui/browse_thread/thread/6f69bdf753bf7d40
and made a small attempt to implement a workaround, but was not
successfull. As it works in IE 8; I will not try to fix it anytime
soon. First I will make sure everything (or at least most things) work
in the browsers suggested on the Boragonet Wargame Rules page, i.e:
Google Chrome 5, Internet Explorer 8 and Firefox 3.5. As I use Firefox
3.0.18 on Ubuntu when developing Boragonet Wargame it will probably
work reasonable in that version of Firefox too.
