Hi Adrian,
thanks for your suggestion. Actually when I came back from work I tried the key on Practice mode and there was some malfunctioning. So I cleaned the contacts with sandpaper and immediately the malfunctioning went away. Whether this was the entire culprit of the problem I had on the air, I will check next weekend on a new activation (I do not have an antenna at my QTH, sadly...) but it looks promising that the problem will be fixed already!!
I am new in CW and I was too shy when cleaning the contacts, I did it with a piece of paper only... I was afraid of damaging the contacts. Ok, I have learned a new thing. Thanks!
Will keep you posted.

Joan,
Hope you don't use regular sandpaper, you will ruin the plating from the contacts!
In my previous post, I've mentioned very fine grained (800 grit) sandpaper used for shining guitar frets, that's the one you should use.
