Is the problem multiple cubes?

Following my problems yesterday with multiple crashes, I started fresh
in a new folder.
I created a database source that connects to AS. I created a report
through the wizard, and when it finished I saved everything, and it
worked correctly from the preview. Everything looked fine.
But when I clicked on the data tab, everything in the designer was
wiped clean. This has happened a number of times.
Could this be because there are two cubes in the database? I'm using
the second one alphabetically, and when I go to the data tab the first
one is displayed as a default.
TIA,
JimNever mind. It's a known issue.
