I'm 73 in Feb.. Seems I am not stating what I say in my posts clearly or members here not reading correctly since getting wierd responses in regard to them. To be clear I have no problem with back button. If I did at an earlier time it was because didn't see how it worked.I guess that would be problem that others have 'don't understand how it works' most of the time anyway. Of course there are viruses vaquelly called redirect or similar which can be difficult to get rid of since security dosn't find and remove them ,MSE for example didn.t find and remove had to find other freeware to get job done I think anybody that had those bugs and got rid of them without paying to get it done knows what I mean. Once again I don't see how compatability has anything to do with back button which controls movement from page to page(in a window?).
