Under the "Find and Replace" sub-window, the "?" tool tip button on the right of the "Regular expression" checkbox causes the "Find and Replace" list to disappear after you confirm "OK" on the regular expression tool tip sub-window. I need to enter something in the "Find" text field to populate the object list first and then click on the "?" button to see the bug's effect. The "Find and Replace" object list won't refresh even if I attempt to reenter the "Find" text field. Closing the "Find and Replace" sub-window and reopening it restores the object list functionality. That tool tip sub-window is bricking the "Find and Replace" sub-window.
