this is strange, but it works: make a message box with
Max will erase the quotes, but if you click the resulting message box (instead of a bang) to open your [dialog], whatever was there before will be erased. So it's not clearing after you enter, it's before, but hey, I think the result is the same.
try it with just
somehow, after erasing the "" there is still something there...ghosts in the machine...ahh, great album ;)
do u often use the max help if you need information about objects, the dialog help shows how to use the symbol message. instead of text you can use an empty symbol or a space ""; " " to end up with an empty enter box when opening. i think it's not even possible to change the dialog title text on the fly once the object is created.
