Prompt Timer conflict

Description

If a Timer statement has been issued then Prompt will not properly wait for input. It is bypassed and the code continues leaving the Prompt dialog hanging. It takes input but it is not taken into the program.

Example code to demonstrate the bug.

print "program starts"
timer 500, [delay]
wait

[delay]
timer 0
print "delay ended"

print "prompt issued"
prompt "Enter something"; a$
print "You entered: "; a$
print "Program ended"
end
