Cursor is deactivated after Ctrl+Alt-combination

I use Mathematica 4 on a Windows XP SP1 computer. As I have a German
(QWERTZ) keyboard, I have to use very often the Ctrl+Alt-combination
in order to write characters like brackets or backslashes.

The annoying thing is that after I release Ctrl+Alt (precisely: first
Alt, then Ctrl), the menu bar gets the focus and therefore the cursor
is deactivated (it's still there but it doesn't blink anymore).
Apparently, the problem is that Mathematica thinks that I want to do
something with the menu because I have pressed alt, but doesn't
"consider" the fact that I have also pressed Ctrl.

Another effect is that Mathematica beeps all the time I type one of
these special characters. I assume that this is because Mathematica
thinks I want to open a menu by a shortcut that doesn't exist.

I didn't have this problem on Windows Me. It seems to be quite
general, because my TeX-editor (TeXnicCenter) shows the same behaviour
and even some Windows applications are slightly behaving like this
(they just underline the shortcut letters in the menu bar when
releasing ctrl+alt, so it's not that bad).
So actually there must be a simple solution.

I would be very glad if somebody could help me on this or on the
problem with the TeX-editor,
