Gimp whimsy about wich monitor start in.

[mrkid]

Hi!. Im currently working in a three monitor setup. Handy. The problem i have with Gimp is that for some reason it starts each time where he wants. I want it starts in the main monitor, at center of the three. It is the main monitor on windows setup. But Gimp sometimes starts at right monitor, sometimes at middle, sometimes at left... Funny! But bother a little, you need to drag it, maximize, etc, before start to work.
I have changed preference in "Windows management" but no change. It still opens where it desires.
Any tip?
Edit: I found what happens. Gimp follows my mouse. If i move my mouse to another monitor after click GIMP icon, gimp opens where my mouse is placed. So... you need to waaaait gimp totally open, to continue working...
