I reported this in the Beta forum, but didn't receive any responses...I guess it probably belongs here anyway...
Most dialogs (such as the find dialog) pop up in the middle of my VS window, which is good. I use VNC with a wide resolution split across two monitors. Dialog boxes such as the "Can't save config", "Do you still want to exit" and DiffZilla's "No more diffs, do you want to close the file now" always pop up in the center of my desktop (splitting the monitors) rather than the center of the VS window. I'd prefer that all dialogs pop-up in the center of the VS window if possible.
