Solution Do not Retract or solutions are not Deploying

When you go to the 'Solution Management' screen of Central Administration and retract a solution (wsp) it seems to retract ok but the status of the solution remains ‘Deployed’. When you try and delete the solution in the GUI you then get an error saying that you must retract the solution first – but it is retracted!So you can say it almost hang mode where you are not able retract or deploying new solution
