Is there some solution to this, like some sort of undocumented setting in the Input Server?  Or something else?  Or should I go back to buying a new balled mouse every few months? (they're dirt cheap but it's a pain having to replace them so often -- yes know how to clean them out, but they still deteriorate eventually).

I have a USB Logitch MX500 and Have no problem in BeOS (or Zeta) What 
type of mouse is this?

By the way any one knows how read lines from a text file that uses not 
only english letters? I have problem with the BFile::Read() the swedish 
letters ÅÄÖ are not reqognised

I found this on one of the older bedevtalks list..but ÅÄÖ are not reqognised

//Function to get a line from a file
bool BeGenApp::getline(BFile *file, BString& string){
    // These are all static so we don't lose 'em between function calls
    BString temp;
    static char buffer[4096];
    static off_t positionInBuffer;
    static ssize_t amt_read;
    string = "";     // Clear out old string
    // Fill up the buffer with the first chunk of code
    if (positionInBuffer == 0)
        amt_read = file->Read(&buffer, sizeof(buffer));
    while(amt_read > 0){
        while(positionInBuffer < amt_read){
            // Return true if we hit a newline or the end of the file
            if (buffer[positionInBuffer] == '\n') {
                positionInBuffer++;
                temp = string;
                temp << "\n";
                printf(temp.String());
                return true;
            }
            string += buffer[positionInBuffer];
            positionInBuffer++;
        }

        // Once the buffer runs out, grab some more and start again
        amt_read = file->Read(&buffer, sizeof(buffer));
        positionInBuffer = 0;
    }   
    return false;
}
