Unintentional drag without holding down mouse button

[Timberline]

On three occasions now I have gotten into a supposed drag state in the server tab with no intention and no cue (that I noticed) that I was in that state. The first time a whole document root and thus its site "disappeared" for a while. After finding it, I assumed I must indeed have dragged it into the adjacent folder in haste with a sloppy-slidy click or double-click, because I was rushing half an hour before a big demo.

But now I see it is possible somehow to unknowingly initiate a drag state (by sloppy click?), then scroll around for a while (many seconds) with no mouse button held, then click on a folder and Filezilla "drops" or attempts to drop the folder it thought you were dragging. At least in the server tab. I'm reluctant to experiment too much with trying to duplicate this.

I haven't been experiencing this in any other application.

It's dangerous enough that I looked all around for an option to disable dragging of files or folders in Filezilla but apparently it can't be disabled.

I really like FZ but now I'm very nervous I'll damage a site again without noticing. This third time, the only reason it didn't happen was because the folder I clicked was a subfolder of -- again -- the document root. A less obvious moved folder could go unnoticed.
