I came across an interesting problem where a colleague of mine could drag a window to place it in a convenient spot, but could not drop it. It was a pop-up generated as a legitimate part of the works web site, but when the left mouse button was released then the window continued to be stuck to the curser. Right clicking would release the window so you could click on an option or another part of the screen, but as soon as this was done the window attached itself again.
This does not happen often, but is bad when it does ad this particular colleague is in a help desk situation and when it happens in the middle of a call it is impossible to continue without refreshing the page, and therefor losing the place in the problem.
Any ideas? - as always a beer of the very alcoholic virtual kind is on offer to the first correct respondent :^)
