I'm using CompactGUI.mono 4.0 beta 6.

when i was trying to compress my 42.2GB folder with ISO files(yeah those Burnt CD files) the compact GUI suddenly frozen and had no response status for 5 minutes and crashed

then i tried to re-open the app but it didn't opened

so i restarted my computer and suddenly the compressing seems finished (the file's size was dramatically reduced to only 17.1GB)
but ISO files were completely bricked

so i tried to decompress it... but it won't work
Pressing Uncompress button did nothing at all

it's most likely my computer's issue but i'm curious that is there any similar issues like this?
