Pressing refresh twice

[limelect]

Pressing the refresh button twice gave "DosCommand still running"
so I added

DosCommand.Execute;
repeat
Application.ProcessMessages;
until FFinished;
DosCommand.Stop;<<<<<<<<<<<<<<<<<<<<
CleanPackageList;

my preferred method is to disable the possibility of refreshing in the first place...

actRefresh.Enabled := False;
try
  // refresh code
finally
  actRefresh.Enabled := True;
end;

I committed that change.
