Hi Jeremy, I have several X11 windows (all belonging to a Wireshark process) that don't get individually spread out in any of the Expose views (F9: all windows, F10: this app's windows, etc.) -- it treats all of the Wireshark windows as a single group, leaving them stacked on top of each other while it rearranges the display. Other X11 windows that exist at the same time get broken out and treated independently like they should, it just seems to be something different about Wireshark's (v1.2.1) windows (statistics, analyze, about, etc.) that is affecting how the wm treats them. Is there anything I can gather to help diagnose? Thanks, - Brian
