### Environment
- OS: macOS (MacBook Air)
- Wine version: 11.0 (Stable/Dev)
- Software: ACD/ChemSketch (Freeware) 2025.2.1
- Build: 147869 (26 Jan 2026)
- File Version: C65E41

### Problem Description
The application ACD/ChemSketch 2025.2.1 crashes instantly when attempting to
copy any drawn object or chemical structure to the clipboard using Ctrl+C or
the "Edit -> Copy" menu.

### Steps to Reproduce
1. Start ACD/ChemSketch 2025.2.1 in a clean WINEPREFIX.
2. Draw a simple structure (e.g., a benzene ring or a single bond).
3. Select the structure using the selection tool.
4. Press Ctrl+C to copy.

### Actual Result
The application terminates abruptly with a crash as soon as the clipboard
action is triggered.

### Expected Result
The structure should be copied to the clipboard for internal use or for pasting
into other applications (via Wine's clipboard synchronization).

### Additional Notes

The issue persists on a clean Wine 11.0 installation without any DLL overrides.

This version of ChemSketch is very recent (Jan 2026).

The terminal output shows multiple EMF_Update_MF_Xform World transform failed!
errors, followed by fixme:ole:OleQueryLinkFromData ...,stub!.

It appears the crash is triggered when the application attempts to populate the
clipboard with OLE data and Enhanced Metafiles (EMF).

I am attaching the full terminal log and backtrace as a .txt file.
