Thanks Sean, I just uploaded the files.
Ok, yeah, I'm not sure what happens, that's why I didn't call it a bug. I don't blame neither software, and it could just as well be some weird thing on my system, who knows. Such interactions can be tough to understand.
Anyways, I mean, the issue can easily be avoided once you know it, but it took me quite a while yesterday, so I thought I might point it out here for reference.
Interesting, I didn't have any other problems with MyPhoneExplorer, but I noticed when I download files to my PC, it completely blocks the Windows Explorer window (the one I dropped the files on) from interaction. Can't move it, can't minimize it. Oh well...
Edit: But I think it's a nice tool, I definitely should donate a couple of bucks.
