I noticed a strange problem with
wxPython2.6-win32-ansi-2.6.1.1pre.20050615-py24.exe.

On wxPython 2.6.0.0, following worked fine:
Drop a file from explorer or other filemanager to
DrPython opens it, cursor appear and cursor movement is fine.

With 2.6.1.1 prerelease, cursor appears, but then no
cursor key (down, left, right, up, page up,...) isn't working
anymore.
