Hi Peter,
Thank you for the reply, it certainly was'nt my intention to sound unappreciative in any way, quite the contrary,so apologies if my reply sounded as though I was.
Yes, Firefox is my default browser, I'm glad you asked about the number of versions of Opera, I did wonder myself, so I checked on the Opera forum and found other user's have also queried this.
Opera does seem to lock up at times , when check on the Task manager there is usually a list of Opera opening several times and then a crash report.
This is mentioned on Youtube and in in varios forums on the internet which is where I found the advice if Opera locks up to open the task manager and clear all the Opera start ups.
It seems that when a new updated version of Opera is installed doesn't remove the previous version, some people asked about removing the older versions of Opera but were advised against doing so as it may cause problems?
Now you mention this, I had noticed on odd occasions the Opera screen has has gone black when using Firefox at the same time.
Sorry in hindsight it might have helped if I had mentioned this before.
Thank you
Kind Regards.
