In fixing the Windows build a few weeks ago, I simply stubbed out some loader functions rather than porting over the original versions from FrameWin. Fixing this will mean link clicks work again. Patch coming shortly.
Created attachment 11710 [details] patch v1 Re-implements a few bits that used to be in FrameWin, adds a few EventHandler forwarding functions (may not be strictly necessary), and patches mouse message handling to ignore unnecessary move events, so link clicks actually get through instead of being invalidated in most cases.
Oh yeah, I forgot that the patch also updates a lot of the formerly-AbstractShared Windows classes to no longer inherit from Shared<>. I don't know how this is managing to compile on the trunk and how it compiled for me before, but as soon as I started touching my checkout today it (rightfully) broke.
