[SOLVED] Start page project without rights selected after user rights restricted

Hello

After I have changed the rights of my Testuser to more restricted profile, I realized that the last filter for the selected project remains on the last project (no tickets etc. shown) , but after changing the rights of the user shouldn't have acccess to this project anymore.

After switching to "All projects" the selected project doesn't appear (which is as it should be)

I tried to select another project as filter, logging out, logging in, but it switches always to the one which he has no right.
So the other question is: When does a project count as "Last selected, as it is configured in the user parameters default project.

Regards
