Hi Khaled
Thanks for your reply. Yes I tried the icon maroon posted and it was the same error. Before I used mIRC 7.62 and several other versions, down to mIRC 6.16 and it worked always. I added the icons some years ago and never had problems with it. In my first posting I wrote the script line, could that be the problem? Was anything changed there? I looked in the changes of 7.64 and didn't spot anything that could have to do with it
