A few users have had problems with Squeeze Control XL and SBS 7.6.1.

I figured out that it's a bug in 7.6.1 which causes the SBS to not serve up certain icon images to controller clients. The next update to XL (1.0.7) has a fix for it and it should be available soon.

However, it didn't seem to affect everyone, and I think I've figured out why. The bug only seems to show up when you're upgrading from an older version of SBS without first uninstalling the older version.

So if you're encountering this problem, try completely uninstalling 7.6.1 and then reinstalling.
