mouse curser show RED symbol of no-entry, which doesn't allow slide and drop from palette
With a Microsoft OS, the Mouse curser shows a no-entry symbol in RED and in not interactive when trying to slide and drop elements from the palette. normally the mouse curser shows a grey no-entry symbol see screen shot of a correct mouse curser" which changes to a "hand" symbol where you want to drop the element - dynamics, lines, etc... from the palette.
Any ideas of where to correct this mouse curser problem?
thanks in advance
