Forms maintained by PDE Forms is owned by UA. What are the steps to reproduce this? It has happened to me when quitting an RCP application, which uses a Section. The section is populated with a Composite that holds other controls. (In reply to comment #4) The section is placed inside a view. This is the same problem as was reported in Bug 319127. Closing as duplicate. *** This bug has been marked as a duplicate of bug 319127 *** That's true, I'm also using the NO_TITLE style. |
