as has been mentioned (i should respond...), removing keyclone is as simple as deleting the folder. there are no other files outside of that folder that keyclone creates. when you install it, it does not put dlls in the system folders (i hate when programs do that) and it does not impact the registry (i hate when apps litter the registry as well). and yes, there is an installation program... it's the thing that has the 'unzip' button. is it installShield? no.. why should it be? does it have a registered uninstall/change piece that hooks into windows? no, that would be unneeded and dealing with 'add/remove programs' can be a very slow process.

as for the freeze on exit... yes, that is one of the 2 major bugs (the other being the mouse being pushed outside one of the maximized windows). there is a known work around... don't click the X to exit. once you do, it does freeze on some machines. instead, just right-click the titlebar or tool tray icon and select 'exit'
