Not a keylogger , or maybe , to detect bad random keypresses

[erdemyy]

I have detected that nearly all of my alt+ triggered macros do not release the alt key for several seconds. So its not just one particular macro. I have included sending alt keypress in my macros as a workaround :S
However this doesnt always happen , but im using QM macros very frequently and couple times in a hour, alt key isnt released and regular pressed like s / f , translate into alt+s , alt+f and my output freaks out :/
