Wierd exception when calling SetAutoHideMode(ctrl, true)

[Udi Dahan]

Hello,

I've come across an odd occurence. I am attempting to dock a control to the left, set its auto hide mode to true, and then hide it in one method call.

Something like:

dm.DockControl(ctrl, this, dockingStyle.Left, 150);
dm.SetAutoHideMode(ctrl, true);
dm.HideAutoHiddenControl();

Sometimes, the call to SetAutoHideMode fails giving me a NullReferenceException. I've mucked around the source and I've found that it fails in FormController.AdjustLayout(...) at step 3 when calling this.ctrlHost.Update(). I noticed that the x value of rcclip was -1 when this occured, if that's of any relevance.

The truly odd thing about this is that all of a sudden this began occuring, one day everything's fine, the next, the exact same code starts acting up. Even more confusing, other calls to this code work just fine.

Please HELP !
