Some general thoughts on presenting problems.
I find the general idea of how problems don’t seem to be valid, and then they are, doesn’t get lost on anyone. It appeared SJLPHI appeared to be the only one with the issue regarding the Shift+drag. Other people tried “the same steps” and found no problem. It looked like he was the only one with the issue. I had been having the issue and finally searched for it and this was the only instance I found. So now there were two of us, but still others tried the same steps with no issue.
However, “the same steps” were found out to be different. While there are cases of someone posting things like, “My computer isn’t working right. Please help”. one can’t blame SJLPHI for not posting the exact steps. He didn’t really realize what they were. Neither did I, and the issue only appeared some of the time. It was only after I persisted in trying it over and over did I stumble upon the correct steps.
I usually use separate instances of dolphin rather than dual panels. I presume SJLPHI does, too. However, there are others who use dual panels. We each presume and assume.
For me, I am very careful about dragging files as I have accidentally released files into the wrong directory, then have to search for where they went to. This happens when you release the mouse button while still moving the mouse and it happens to slide up or down a directory. So I got in the habit of not release the mouse button, whether directory or not, until making sure I stop moving. It transformed into an easy habit of not pressing the shift until right before releasing the button.
So what I’m saying is, my past experiences causes me to actually do things differently than others without those experiences. (Which, of course, isn’t saying anything dramatic). But we may not realize we do them differently, we say we click and drag the files, but actually are doing it differently. One cannot blame anyone for not saying it explicitly, because we do not realize what we are actually doing. It was only after quite a bit before we find out some are holding the shift to start with, others at the end, and maybe others in the middle.
Not that knowing this makes things easier when there seems to be conflicting reports in the future. But maybe we can consider if everything is as the same, even if it appears to be a simple straightforward step.
