CF Builder 2 slow on closing files issue

This is an old issue that still has not been resolved

When closing a file on CF Builder 2 it takes a long time for the file to close. This used to happen on Windows XP. I have a new PC with Windows 7 and reinstalled CF Builder 2 but the issue closing the file continues.

I have to do the following for that to stop.

1. Closed CF Builder
2. Renamed the file workspace\.metadata\.plugins\com.adobe.ide.editor.cfml\foldings\foldings.data
3. Started CF Builder

However, after few hours CF Builder 2 becomes slow again when closing the files.

Is there any fix for this issue other than the temporary solution above?
