Hi Tim, and thanks for this great plugin.
Recently, I upgraded computers, and once I got everything installed, including: Paint.net, your plugin, and Windows 7, your plugin would not work anymore.
I tried uninstalling Paint.net, downloading a fresh version of your plugin. Nothing.
What happens when I attempt to use your effect is that I get the effect applied to my file, but the dialogue/control box is nowhere to be found.
Further, if I click anywhere on Paint.net, I get the Windows "D'oh!" chime. It seems like the controller is hiding somewhere, but I have tried <Alt>+<Tab>, and shrinking the Paint window, and shrinking my canvas, and turning on and off all the Paint.net windows. Your dialogue box is nowhere to be found. Any suggestions?
Thanks!
