I don't get 'a script has stopped running' dialog box and I just used a browser as an example. All of my browsers do crash occasionally except for lynx and dillo. I posted a question similar to this before and I think the consensus was to restart X which is pretty close to rebooting and we don't reboot linux to fix a crash of coarse. I got fed up and and opened up a text console and 'killlall opera' and mouse worked once again. This is much better than restarting X. What I was thinking of is to kill whatever has control over the mouse but X should only have control over the mouse so I need to know how/why an application has the ability to make the mouse useless. Data should go from the mouse controller to X and then X needs to send data to the application that should be using it. This is simplified of coarse but I started this thread to make it more precise.
"Opera has crashed". So what. Why does'nt the mouse freaking work?
