Hi,

First of all : Your system details show that you need to update your Adobe Flash Player, as you are running a very old version, which can cause problems. Would you please uninstall your current version and install the latest version, which is 28.0.0.161

To uninstall (you'll have to scroll down to Linux) : https://computers.tutsplus.com/tutorials/how-to-uninstall-disable-and-remove-adobe-flash--cms-24414

Then install the latest version : https://get.adobe.com/flashplayer/otherversions/

Note : some 'extras' may be offered in the download.

Then, would you please take a look at this article, especially the section How to remove a single website from my history

Can you attach a screenshot or give more detail of what is wrong?

• use a compressed image type like PNG or JPG to save the screenshot

Thanks, Happy112, for replying promptly. I downloaded both the npapi and papi versions, unpacked and saved the two .so files in .mozilla folder. Doesn't help. And Cor-el (any relation of of Kal-el?), perhaps you have spotted the right area.

Asking you to update Flash was meant to keep you from running into more (other) problems in the near future .....

I'm glad you did - well done  !

I reinstalled the nVidia driver as well. The version NVIDIA-Linux-x86-304.125.run because I have a nVidia card GeForce 6150SE nForce 430, because I run the 32 bit version.

I will now proceed to install in the 64bit version also. Let's see what happens.

But shows the text in the panel, "Drag Me!", then silence.

Then what do you expect me to do? Any advice please?
