I'm using UltraWebGrid and I can observe that the memory is not garbage collected even a few hours after the session is closed. Explicit 'Dispose' call doesn't work in my case. I override 'Dispose' method in the form which keeps a reference to an UltraWebGrid object:

    public override void Dispose()
    {
        base.Dispose();

        uwg.Dispose();
    }

The reference seems to be still kept by the ScriptManager (as it can be seen in MemProfiler). I'm using UltraWebGrid 8.2. What shall I do to solve the problem?
