ColdFusion builder has been freezing on me at work lately and I could not figure out why. Basically every time I started it back up It would freeze and never recover. The only way to use the editor again was to delete the workspace or start a new one. This was a big pain in the butt for me because I had to import all of my old projects. in. I was digging through the logs and came across this.

Something was obviously not loading correctly but I could not figure out why until today when I was coincidently using wireless instead of the LAN. When this happens I have no access to network drives so when I fired up Builder all of my local projects loaded up fine and it never froze up. This led me to believe something was up with all of my old lan projects. When I opened up the .project file I found this. I am not an eclipse expert but what I think was happening is that because we were still using the CF Eclipse nature it was trying to load some old data (dictionary) that was no longer there. I wonder if any of you really smart people out there can confirm this. Whatever the case is Builder is back to working how it should be all because of removing the cfe nature.
