This is a thread that started on the wxperl list, then went off-list

The latest version is 0.38 but soon we will release 0.39
For every tab we have a separate STC instance so we don't need to swap them.

I checked it again on Ubuntu and 0.27 has the same issues with the Hungarian

I'll check this.

We also use threads but not for the document handling.

We do that in Padre::Document load_file and save_file
