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
