Comment 2 for bug 106289

The majority of the posts I found didn't say what distro because the posters were new. Due to being new to linux, I doubt they would have tried a beta, so I'm going to take an educated guess and say no, no one has reported this in feisty.

On the other hand, this has happened in more than one version (edgy and dapper being the only distros I found reported), and I think the related PS/2 mouse bug report goes back further, since it's on bugzilla. Because it's been recurring, I would also guess that it's not going to magically disappear in Feisty.

Thank you for the speedy attention! I'm sure it will be well appreciated!
