Looks like it is displayed centred.

Richard, any interest in this?

Here I can move the color dialog to a other position. After closing and opening it again the dialog is at the last position. Also closing TB let the position persist.

Scott, please can you check, if after moving and closing the dialog, it opens at the last position? If not, could you try the same with all extensions disabled (see help menu)?

I tried it by manually moving the color dialog (& pressing OK), then re-opened the Color dialog, it opens again in the center of the 2 screens.  I also tried it with all the Add-ons Disabled, it had the same result.

Okay, and this is the only TB dialog which behaves like this? You tried the other insert dialogs?

What graphics card/driver are you using?
