By having msctf.dll by-passed I appearently really have fixed my problems...
and of course I have a back-up copy

some claim, that this file would cause lag, but personally this whole issue seems to be rather unique to X³ and "foreign" experiences will not help us too much...
And I prefer my work-around to deinstalling it

Just in case anyone wants to know what I have done:
1.) go to your windows\system32\ folder
2.) back-up your msctf.dll file
3.) rename you msctf.dll
4.) copy any other *.dll file into your folder, which is named msctf.dll
5.) reboot your machine
for some reason windows keeps on creating a new msctf.dll file over and over again, so you cannot just rename/delete it...
