This bug is still present in ESP Basic 3.0.Alpha 69 under very specific condition

[gdelconti]

Simply add one "delay x" statement to the above example, like this:

msgbranch [mybranch]
print "set the branch"
wait

[mybranch]
myColorVar = msgget("color")
print myColorVar
delay 10 ' JUST ADD THIS LINE
let myReturnMsg = "You Entered " & myColorVar
msgreturn myReturnMsg
wait
