VueScan is a very popular non-FLOSS, but cheap professional scanning software. Another time I will write a review. For now I want to focus on getting it to run on the newest Ubuntu version 11.04 Natty Narwhal.
Starting VueScan by a double-click seems to do nothing on 11.04 while on 10.10 it worked perfectly. Actually what happens is that there is a bug in compiz that has the effect to not show VueScans windows, when actually it already started.
For now there is no fix and you have to live with the workaround found on ubuntuusers.de to logout of your current session that I assume is a Unity-based session. Upon a new login choose “Ubuntu Classic – no effects” and VueScan will start normally.

It is also possible to disable the window decorations in compiz, after which VueScan will start correctly. Window decorations can be enabled again after VueScan has been started.
It’s still a kludge, but slightly less of an annoyance than having to log out and start a new session.
To adjust the compiz settings, it is probably easiest to install the compizconfig-settings-manager which will then show up in the System Settings Control Centre.

Hey Neil,
Thank you for your comment!
I just tried your workaround and you are right, it works like this as well without the need to end the session!

I have used VueScan on Ubuntu 11.04 (32bit) and it worked without any problems.
