Is there a reason the Settings dialog is very slow?

When I click to open settings it takes over 40 seconds to open, and opens behind other windows but the (DF) taskbar button isn't blinking.

When I make a change (like adding a compatiblity setting) and click Apply, the dialog shows a wait cursor, the main dialog buttons gray out for a few seconds, then come back, then the dialog moves a few pixels down and to the right and the Titlebar shows Not Responding for over 40 seconds.

I am on an nVidia video card with Windows 7 64-bit Enterprise behind a authentication required proxy server.

Sorry I hadn't looked at this in a while. It is still slow to open in 7.2.0 beta 2. Attached are my settings backup.

The rule pointed to a server that was migrated to a new name. I changed the rule to use my mapped drive instead.

Perhaps the timeout could be reduced on that?

Thanks!
