Copy from MessageBox shown by pipeline component shows windows error on Ctr+C [Zsolt]

[tznind]

Describe the bug
If a pipeline component in a multithreaded execution (e.g. Extraction) uses IBasicActivateItems.Show and the user hits Ctrl+C on the dialog, this causes a windows error popup under some circumstances

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

I think that we need to handle RequiresInvoke in Show (for windows client).
