Wrong URL opening browser

Recently I deployed a project 'Pro01' in Mendix 3.3.1. Strangely, all projects deployed earlier in 3.2.0 are visible on the Mx 3.3.1.-startpage under "recent projects" as well. After deploying project 'Pro02' in Mendix 3.2.0. tried to run 'Pro02' by pressing 'Open browser'-button. Surprisingly, the URL http://localhost:8080/#1340891794734-2 is called from the browser (internet exporer) linking to the 'Pro01'- instead of the 'Pro2'-start page. Seems to be some 'browser-cache' problem. Please help me out.

Is the other application still running? If not, clear your browser cache and try again.
