Using SuSE8.0 I haven't seen that bug again for some month. That's why I
can't reproduce it in the latest KDevelop-2 versions.
The bug itself is really easily to check. The cursor disappears when
QextMdiChildView::focusInEvent() wrongly returns in its first code line
without further processing the method. The return out of that method has
only to be done when there is some kind of recursion of focus setting.
It is necessary to e.g. avoid unnecessary draw events of the editor
widget which would e.g. slow down the popup-menu of the main menu bar.
So if the cursor disappears, check why focusInEvent() returned and
analyze why it was wrong in that case.

Once we ran Purify over QextMDI on Win32 and it was OK.
