Hey there!
I'm so sorry if this has already been mentioned, rejected, accepted, or anything -- but I'm going to post this anyways :P
I use WinSCP a lot, and I really love it. It seems bug free and works how it should. However, certain tasks hang the UI. It's really annoying, as it shouldn't happen if a proper threading technique was used.
Is there any way we could see tasks that currently hang the UI being threaded better?
Tasks such as logging in, copying files, and changing directories hang the UI right now.
