I'm observing the same issue with various programs in Darwine. I've only tried using v1.1.1 so far using XQuartz 2.2.3 on MacOSX10.5.4 (Leopard). Some installers have a progress bar, which shifts down by about the height of the top Mac menubar every time it progresses or other information changes in the dialog. Attempting to install Poser Figure Artist is successful, but I cannot register it, as the menus shift down so fast it is not possible to grab them before they go offscreen. I've just asked about it on x11-users@xxxxxxxxxxxxxxx
