I consolidated my A4000D by copying two HDs of stuff onto a single larger HD which was previously Amiga formatted and sold to me from ebay. Took awhile to get the various jumpers and all but finally it was done and I had freed up a plug for a CD drive... which also finally works. (YAY) but in the process I noted that the image on the screen had left shifted about 1/2" so that file lists in Opus lost the first couple of characters.
In some progs I could resize the window and move it to the right to reacquire the edge of the window, but some did not allow that and I just had to fake it. The monitor is a C= 1960 and the OS is 3.1. I tried the Horz phase control and the 'width' toggle but they changed the screen, and not the windows in the screen.
Since I had not changed any settings in consolidating the contents of the machine, merely copied them from one HD to another, what would cause this shift? I may not have gotten all the files moved over if at some point I got confused, but the attempt was made. But still, it is nice to have those first couple of letters of a word, so that I am seeing "Workbench" instead of "rkbench", likewise in reading my startup file it's good to know which lines have a ";" at the begining.
