I am still using the Flash CS5 IDE for my interaction mockup sketches. I am thinking of switching to Flashbuilder or the open source alternative FlashDevelop. One thing that bugged me for a day or two was that the code hinting suddenly stopped working. I looked on some forums and was advised to clear the codehinting cache etc. One post said that there should be an icon in the bottom right corner of the code editor that was informing the user about this. It is really hard to notice if you don’t know where to look for it. it looks like this.

As you can see I had to many files on my class path, so what I needed to make this work was to remove some of my files on my class path.

And my Code hinting is back to its sweet self  ! Hurra !
