Warning pop-up

This is not such a big deal but is just annoying to deal with in every drawing...

basically in the middle of every drawing I get a pop-up about a script that is making adobe flash player to run slow or something like that, all I have to do is push OK and continue drawing...

one day the error came up but I clicked on the browser and the error pop-up went behind the window, so I ignored it and tried to continue, but I could not draw after this, since I had little time, I could get to the warning window on time and I lost the panel...

Is anyone else getting this? Is it my PC or is it Drawception?
