Does anyone have an elegant, simple idea for a script which could run in the background and check the contents of the system clipboard continuously? I'm trying to find a way to open a web page from inside mini vMac (a simple Mac Plus emulator) where I have several Hypercard stacks running. This emulator does not allow any interacton with the host OS (X) machine, except for two little apps which get and put clipboard contents from and to the host machine. So I hope to send a flag and a URL to the host machine from vMac (via the clipboards) and have Applescript on the host machine notice it (more or less immediately), extract the URL, and load it to a modern browser. And something vice-versa, which I can write a HyperTalk idle script to notice. Any ideas? mbossiere
