Have you tried shutting down and restarting your computer?
I restarted. Still the same. I briefly looked around to see if there are any other windows that are blank or any other modules that are broke and it seems that only the Auto Vector Mask is the only one. I'll continue to troubleshoot. Thanks.
You can replace the "Auto Vector Mask" SWF file present at the "Fireworks installation folder/Configuration/Commands/Creative/Auto Vector Mask.swf ".
If this doesn't work, then one of the reasons that it could be happening is if Firebug or Flash Firebug is installed.
If you have either of those, can you uninstall them and relaunch Fireworks.
Let me know if it works.
