On Windows XP Prof. SP2 (German) with running latest
DM2 there is a conflict with Windows Task-Manager.
"Windows Task Manager --> Options --> Minimize on use"
has no effect, even it's been added to Settings ->
Exception. Also when you exit DM2 the problem still
remains. Only after a reboot without auto-run DM2 it
minimizes to tray as it shoud, but after starting DM2
it's no longer possible.
