Since some recent updates of ubuntu 10.10 , the thunderbird portable refuses to run properly in wine. It used to work fine, but now it says that it can not run on read only media and copies the TB to hard drive first.
Installed is TB on usb flash stick, so there should be no problem with writing and when I try to find about rights, it tells me the rights are unknown which is of course the problem.
Did someone observe the same?
