Hello. When running Windowed command.com under Win95 or 98 booted from DosBox-X I get problems with installing some programs (e.g unofficial service pack) I think it is because there is something that freeze commands that run in backgroud.
Why I think? because I also noticed problem when using COMMAND.COM in Windowed mode.
When I type on keyboard system (and mouse) freeze for a few seconds.
Steps to reproduce the behaviour
Boot system
start COMMAND.COM
type any letter
system freeze for a few seconds
Expected behavior

Describe the bug
Hello. When running Windowed command.com under Win95 or 98 booted from DosBox-X I get problems with installing some programs (e.g unofficial service pack) I think it is because there is something that freeze commands that run in backgroud.
Why I think? because I also noticed problem when using COMMAND.COM in Windowed mode.
When I type on keyboard system (and mouse) freeze for a few seconds.
