Eucon prevents "allow button" resolving systems extensions blocked

[JeromeS]

Maybe it's already discussed here somewhere at the forum but I had a problem where I couldn't press the "allow button" after installing drivers for hardware:
discussion example here:

It seems that also Eucon being active prevents you from allowing drivers.
After stopping Eucon I could press the "allow button" immediately.
Costed me a day of work to find out, so it might be useful to others..
cheers,
