annotate src/window.c @ 3068:0787bb5f387b v7.3.306
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.
