I have observed that when I have mutiple wxStyledTextCtrl in different places only one of them processed shortcuts and the rest does not get a chance even when they have a focus.

Here is the scenario:

Let say STCs are s1, s2 and s2.

If focus is with s1 Ctrl+C copies selected text from s1 - Good
move cursor to s2 and do Ctr+C, it copies selection from s1 - Bad
move cursor to s3 and do Ctr+C, it copies selection from s1 - Bad

Here is git diff for STC sample to test.

Just apply the patch below and then select text on an open editor. Go to menu (Window->Minima Editor) and it will open two more editors in a dialog. Try select text in any of the two and do Ctrl+X and see that it cuts text from first editor not the current.

Under which platform have you observed this issue? I briefly tested wxSTC under wxMSW and haven't seen any strange behaviour with clipboard.

Hi sorry for late reply. I tested only under OSX. Currently I don't have access to Windows nor Linux. When I do I will test with same app to see if they are affected too
