TC copies message box text instead of lister text

[MVV]

Open lister, then open MRT and choose 'manually edit names'. When TC will open editor, switch to lister and try to copy some text. Then paste text into editor - text will contain message 'Click OK when you have closed the editor to load the changed names!' instead of selected text in lister.

Confirmed for Ctrl+C
Not confirmed for Ctrl+Ins

This is a "feature" of Windows, not TC. Ctrl+C will always copy the text of a message box if one is open in the current process.

I thought that this shortcut is processed by window procedure of message box. So I don't understand why it receives this keypress when lister window is active.
Maybe it is another VCL bug or limitation?

No, it's because the MessageBox() function takes over the message loop handling (GetMessage/TranslateMessage/DispatchMessage), and the Ctrl+C handling seems to be done within that message loop.

[MVV]

That's strange because GetMessage should return only messages that were sent to specified window but message box and lister have different windows...

Yes, but since they are the same process, they share the same message loop. If you want to avoid that, you need to start Lister as a stanalone tool via /S=L command line switch.
