DockPanel Suite

Invalid Content: ActiveContent must be one of the visible contents, or null if there is no visible content.

all of a sudden, started getting this message when attempting to execute:

Form1 form1 = new Form1();
form1.Show(dockPanel1, DockState.Document); // THIS WORKS (PUT IT IN AS A TEST)

QueryResultsForm qryResultsForm = new QueryResultsForm();
qryResultsForm.MdiParent = this;
qryResultsForm.QryText = qryText;
qryResultsForm.SConnectionString = sConnectionString;
qryResultsForm.Show(dockPanel1,DockState.DockTop); // THIS FAILS, GIVES ACTIVECONTENT ERROR

it has worked previously. I

I saw references to this problem in SharpDevelop (http://community.sharpdevelop.net/forums/p/4273/12255.aspx
and
http://community.sharpdevelop.net/forums/p/4144/11887.aspx#11887

but unclear what the proposed resolution would be in my case, the suggestion in the latter thread referenced above seems to have something to do with ICSharp.

Any assistance much appreciated, thanks in advance.
