>But as the tab captions don't have hotkeys and the dialog has memory (it displays using the last configuration used) it seems that it will be impossible to show the performance tab programatically.

If the dialog has a memory, I'd go hunting around for a registry key to set for enabling the tab; it's likely to be platform-specific, though.
