First image:
~ Top two grabs are of a cash table with PT4 HUD and OI playing nicely. Note that the title bar for the OI window 'matches' the Pokerstars title bar with the addition of the words "Omaha Indicator for".
~ Bottom two grabs are of an MTT with PT4 HUD running and OI started but not yet aware/imported/scanned a hand. Note that the OI window title bar etc etc etc.
Second Image (four hands after the image above):
~ Top two grabs are of the cash table with PT4 HUD and OI still playing nicely. yadda yadda about title bars.
~ Bottom two grabs and the PT4 HUD for the MTT table has disappeared. Stopping/restarting HUD has no/limited effect (if a HUD does appear it might be on the PS table window or it might be overlaid on the OI window... either way it will soon go 'poof'). OI continues to perform as expected. More yadda yadda about title bars.
Please note that the MTT, the cash table, PT4 HUDs and OI were all active at the same time, until the PT4 MTT HUD fell over. In reference to the 'window names', I am of course only going by what I see. What the Microsoft O/S calls these 'windows' at a technical level, I have no idea.
