- Fixed: Icon thread (used to load icons and calculate dir size in background) may stop when adding files to background transfer manager
- Fixed: When packing each selected file/folder to a separate archive, the selection was no longer cleared after packing
- Fixed: Updated Chinese translation
- Added: Log function for icon thread: wincmd.ini [Configuration] DebugIconThread=1 to allow test why icon extraction or dir size calculation hangs (=2 for more details)
- Fixed: Use old function to check for infinite loops in Alt+Shift+Enter function (count directories), it may be responsible for the failing of the function
