Hi,
I found out that somehow I am not able to type @ on my Model M. I have the 1391403 version that uses an ISO layout without the windows keys. I verified that all the required keys work (Alt Gr and q in this case). I can insert other special characters that require Alt Gr like Alt Gr + '+' = '~' and 'q' works as expected. My primary OS is Windows 7.
Do I have to install another driver? It is very hard to search for: 'ibm model m' @ sign not working
