when using the 4.2.c release and using IE9 (9.0.8112.16421) as client, the dashlets which have configuration buttons (in the title bar), like the wiki dashlet for example, are problematic:
the buttons, which are invisble when the mouse isn't in the dashlet box don't become visible when the mouse is moved into the dashlet box. They are not even rendered its like they don't exist.
When trying to debug, I can see that IE complains about a SEC7115 (":visited and :link styles can only differ by color. Some styles were not applied to :visited." http://msdn.microsoft.com/en-us/library/ie/hh180764(v=vs.85).aspx ). I'm not sure this is the source of the problem though. I'm currently trying to see what could be changed in the css, but so far no solution. It might also be something that needs to be changed in the share javascripts but there is lots to cover.
Your not the only one, I see it (or dont see it) as well. I cant update to 4.2.d, I just updated to 4.2.C. IM on a Windows Server, and the update was no cake walk. Well, its not as bad now that I have a process, but it takes all afternoon to do.
I found a workaround. It will help viewing the share interface under IE, but some themes (like the light theme) will have some minor problems with it.
