Problem this resource addresses
An inventory window should reopen where the player left it. The supplied implementation opens wndconf/<character>/inventory.pos unconditionally: on a new character, the directory can exist while the file does not. Empty or malformed coordinates can also interrupt Show(). This is a client UI change for private Metin2 administrators who maintain their own Python root and client source.

What M2City changed in r1
The inventory instructions now call m2city_window_position.py. Missing/unreadable files and invalid coordinates fall back to the normal window position. Saving creates the parent directory when needed and handles ordinary I/O failures. Coordinates are clamped using both screen and window dimensions, keeping the whole window reachable after a resolution change. Character/window path components reject separators, traversal and control characters.
Original instruction text is retained separately as M2CITY-UPSTREAM-uiinventory.py.txt. The original supplied RAR has SHA-256 d5351da4fe1c9eed5cf5c00c9f860cadd5c7f7747ecef43335929f6fae588e89; the download below is the patched ZIP, with its own checksum.

Integration order
1. Back up uiinventory.py, interfacemodule.py and your client source. Compare the included search anchors with your branch; these files are instructions, not complete engine files.
2. Merge ENABLE_SAVE_LAST_WINDOW_POSITION and its Python constant export consistently. This resource does not require a database migration or game-server change.
3. Pack m2city_window_position.py into root and use the replacement SetLastPosition/SaveLastPosition methods in the included uiinventory.py instructions.
4. Keep restore after the normal Show and save before Close/Destroy hides or destroys the visible window. Reconcile your equipment-tab positioning hook if your UI has one.

Checks completed and what to test next
Nine host-side regression tests pass under Python 3.13: missing file, save/read round trip, empty/corrupt coordinates, negative coordinates, resolution change, oversized window, unsafe names and a blocked save directory. The helper uses legacy-compatible syntax, but its Python 2 interpreter and Metin2 integration have not been executed. Run the included test_window_position.py, then check first login, close/reopen, resolution change and a second character in a disposable client. No game binary was run.

Credits and variant identity
The public release reference credits Aslan. The owner's supplied file was named Dracarys_Save_Windows_Status_Position.rar; that filename alone does not establish a different original author or an exact upstream revision. M2City claims only the new helper, defensive changes and regression tests. The helper/test licence is separate from the upstream resource.
