i'm not sure if this bug has already been discovered, or maybe i'm doing something incorrectly to begin with, but, i've observed that after i switch to another application using alt-tab (i.e like put dosbox aside or something), the ESCAPE key stops functioning, i'm not sure if it's me incorrectly halting the emulation or something (because like in vmware, there's the ctrl+alt combo, maybe it's something like that i missed?)

any help would be appreciated, thanks!
