Has anybody noticed a conflict between VirtualBox and AutoHotkey on a Windows host? It appears that their keyboard hooks can conflict, resulting in AutoHotkey scripts eventually becoming unresponsive (reload required). Other symptoms seem to be modifier keys getting "stuck" in the "down" position, so keypresses end up being alt-keypresses, for example. The clipboard also stops working properly in the virtual environment. These symptoms appear only after a virtual machine has been running a while under heavy use.
