When I use my OTB button on my external HDD :
- it takes a dozen of seconds...
- ... then the window of B4all appears (even if I set "Show Nothing" in option)
- ...it takes a ten of seconds again before seing something moving in the window and the backup starts
- ... a few seconds later the backup is finished (I've tested with a directory containing 3 empty text files, and I think the backup takes too long for such files)
Can you make a lighter and faster process? Actually its seems like your software is made with Java and is sooooo heaaaaaavyyy.... that it taaaaaakes..... minuuuuuuuutes to staaaaaaaart

Seriously and old version of B4A I have is way faster than your last release. It's a pain to have a window poping and freezing a bit when we want something hidden and immediate.
