Thanks a lot. The Ask toolbar created this problem. Another problem is: When searching on the web via Google, normally it is possible to type a few letters and then look what appears and then click on the wanted word(s). A number of word(s) ineed do appear, however it is not possible to select any of them as ws possible as mentioned in olders versions.
