Pasting randomly fails after installing CopyQ

I have some old VBA macros that operate on CAD documents (not AutoCAD). These macros activate one document, locate a specific entity, execute `Selection.Copy`, switch to another document, and then execute `Selection.Paste`.

I think that the CAD application uses a temporary file to handle clipboard data—placing only some metadata into the clipboard—but I don't know how to confirm this:
- The copy operation creates a file containing the entities to paste and places a metadata clip in the clipboard.
- The paste operation checks the clipboard, and if everything is consistent, loads the file into the active document.

These macros have worked reliably for over 20 years. However, after installing **CopyQ**, the paste occasionally fails. The failure rate is lower if I avoid interacting with the system—about 5%—but increases significantly (up to ~20%) when I perform unrelated actions, such as clicking a link in a browser.

I added some code to detect paste failures. When detected, the macro pauses, allowing me to manually re-trigger the paste and continue execution during debugging. While this isn't a suitable workaround for production, my development machine doesn't typically handle production tasks, so it's manageable for now.

I've used this macro setup for years:
- No clipboard manager initially
- Then **ClipClip** for about 3 years
- Only recently switched to **CopyQ**, and that's when the issue started

So yeah, here’s a bug report that only happens on my machine, while debugging VBA macros interacting with a custom CAD application. How do you even fix that?

Any suggestions?
