When the open files drop list is used to change to another open file the cursor's focus is lost on all files
until something interrupts focus ie. preferences are opened. It is not apparent what has the focus. Files
also cannot be navigated with the ctrl -> or ctrl <- commands or the use of backwards and forwards
jump-list commands to follow code.
I believe this is another manifestation of issue 60235

For this usecase I have a fix ready, however only on 1.4.2 jdk, on 1.5 it's
still not working.
