Hi all, i hope this is the correct forum to post this.
i have a problem with eclipse ever since i installed the new webtoolkit
i'm working with version 3.2 with wtp.
the problem is i can't save resources or exit in an orderly fashion.
i get the following error when trying to save:
Problems occurred while trying to save the state of the workbench.
Internal Error

and when trying to quit:
Problems occurred while trying to save the state of the workbench.
Internal Error
