Paoloc,
We have not seen this issue, but one thing to try before doing much more. I found a very similar forum entry for RAD. The solutions was this:
Have you tried using -clean when starting RAD? You can add this option to the file eclipse.ini, or you can modify the RAD shortcut and add it there.
and the response:
Worked like a charm!! I went into the eclipse.ini file and put "-clean" as the first line, as you suggested and RAD started perfectly.
So, you might want to try the same thing for RBD in its shortcut or eclipse.ini
I also found a reference to an eclipse option named -clearPersistedState that might help. This can also be done on the shortcut or the eclipse.ini
Let us know what happens.
