Command Issues

Hello,

This isn't a major issue but more of a tedious issue. Every so often whenever I am trimming and use the command "TR" I get another command instead. I attached a .jpg and highlighted the instance where this occurred. AutoCAD acknowledges my intended command, cancels it and prompts a new command. The replacement command is never the same or else I'd assume I'm just being clumsy with my typing. Is there anyone else having this happen, if so, have you been able to fix it? I would like to figure this out but at the same time am not complaining about the issue. It simply requires me to hit esc and prompt trim again. It stubs the rhythm of my work but isn't unbearable.

Thanks,

-A
