--- Comment #5 from bas teach2000@basement.nl 2008-12-18 09:53:33 --- I don't know the version that introduced this problem. Teach2000 has been changed and Wine has been changed.
I created a small test application to make the test as easy as possible.
Download the following Win32 application: http://www.basement.nl/temp/Project12.exe This is the RichEdit wrapper component used in Teach2000.
Step 1: Start Project12.exe in Wine. Put the cursor somewhere in the text box and press the button 'b'.
Exp: The code [b] is inserted at the cursor and the text after the cursor is Bold. Act: The text after the cursor disappears.
Step 2: Clear the text box and enter the text 'foo = bar'.
Exp: The text foo = bar is shown, with a blue '='. Act: The text disappears and 'oo bar' is visible.
Tested with Wine version 1.0. Later versions have this problem too.
