Using Matrix in Chrome

Just started using Chrome as my main browser after finding the latest versions of Firefox generally buggy and unstable (on Win 7 Pro). However discovered that actions in the asset map doesn't work (i.e. the copy/link/clone menu doesn't appear on right-click) - I have the latest version of Java (ver 6, update 30) - anyone else using Matrix on Chrome experiencing same issue - is there a fix, configuration issue? Matrix version is 4.4.3.

I think it could possibly be an issue with Webkit, as I saw that problem in Safari before. I downgraded Java and got a new version of Safari and things were fixed.
