Comment 11 for bug 379463

I ran into the same problem. I was able to get around it with the solution described at:

http://www.inkscapeforum.com/viewtopic.php?f=5&t=11525

I believe what got me into this state in the first place, was that I usually run Inskcape on a multi-monitor setup on my laptop. Today, I was unplugged from the dock, thus using a single [laptop] monitor. Also, my "main" monitor when connected to my dock is much larger than my current "main" laptop screen. So, I think it was the case where Inkscape somehow cached/configured/stored the fact that the gradient window was last displayed to a screen location which does not exist in my current setup.

In short, when Inkscape goes to display a dialog - it should first make sure that the location it is trying to place the dialog are in-fact valid and visible, and if not - correct!

Please fix!!
