updated for version 7.3.306 Problem: When closing a window there is a chance that deleting a scrollbar triggers a GUI resize, which uses the window while it is not in a valid state. Solution: Set the buffer pointer to NULL to be able to detect the invalid situation. Fix a few places that used the buffer pointer incorrectly.
