I never want to close winscp at my PC because it cache file browsing and I can browser faster in FTP till I keep it open :) . I did hibernate my PC and continue with cached browsing.
I have activated option "Minimize to System Tray on Minimize" and It lead me two problems
1- Sometimes I mistakenly click X (close) button and here it goes, I lost all cached.
2- When I click WinSCP icon in TaskBar, it minimize to System Tray again which is actually disturbing while we work.
Suggestion :idea: : Make another Option in Preferences Like Skype "Minimize to System Tray On Close" to resolve both issues. :D
