Hi Eva, > I only have the old MC, version 2.4. oh, that is a very old version, and I am not sure if this is 100% compatible with Vista 64bit. It obviously isn't. Can you upgrade to a more recent version of LiveCode (form Revolution)? Seem to be the only way to avoid furhter problems. Best Klaus -- Klaus Major http://www.major-k.de klaus at major.on-rev.com
