I have taken over some code, so I am new to the Planner.NET library.

I have an issue where the instantiated Calendar control (MindFusion.Scheduling.WinForms.Calendar) results in a thread being created with the Highest thread priority. This is subsequently causing massive performance issues (unresponsive, not refreshing correctly) because the thread is hogging processor time.

The thread is created when the object is instantiated in my form's InitializeComponent() method:

Me.m_CalMain = New MindFusion.Scheduling.WinForms.Calendar
' above call resulted in thread created that is running with Highest priority

CType(Me.m_CalMain, System.ComponentModel.ISupportInitialize).BeginInit()

'
'm_CalMain
'
Me.m_CalMain.AllowInplaceEdit = False
Me.m_CalMain.CurrentView = MindFusion.Scheduling.WinForms.CalendarView.WeekRange
Me.m_CalMain.Date = New Date(2006, 11, 1, 0, 0, 0, 0)
Me.m_CalMain.DateTimeFormat = CType(resources.GetObject("m_CalMain.DateTimeFormat"), System.Globalization.DateTimeFormatInfo)
Me.m_CalMain.Dock = System.Windows.Forms.DockStyle.Fill
Me.m_CalMain.EndDate = New Date(2006, 12, 1, 0, 0, 0, 0)
Me.m_CalMain.ItemSettings.ShowMoreItemsCue = MindFusion.Scheduling.WinForms.State.Disabled
Me.m_CalMain.Location = New System.Drawing.Point(0, 0)
Me.m_CalMain.Name = "m_CalMain"
Me.m_CalMain.Size = New System.Drawing.Size(624, 529)
Me.m_CalMain.TabIndex = 1
Me.m_CalMain.Theme = MindFusion.Scheduling.WinForms.ThemeType.Windows2003
Me.m_CalMain.WeekRangeSettings.DaySettings.Style = CType(resources.GetObject("m_CalMain.WeekRangeSettings.DaySettings.Style"), MindFusion.Scheduling.Style)
Me.m_CalMain.WeekRangeSettings.GroupWeekends = MindFusion.Scheduling.WinForms.State.Disabled
Me.m_CalMain.WeekRangeSettings.HeaderStyle = MindFusion.Scheduling.WinForms.WeekRangeHeaderStyle.Title
Me.m_CalMain.WeekRangeSettings.Style = CType(resources.GetObject("m_CalMain.WeekRangeSettings.Style"), MindFusion.Scheduling.Style)
Me.m_CalMain.WeekRangeSettings.TimePeriodHeaderHeight = 32
Me.m_CalMain.WeekRangeSettings.TitleFormat = "MMM yyyy"
Me.m_CalMain.WeekRangeSettings.TitleSeparator = " to "
Me.m_CalMain.WeekRangeSettings.VisibleRows = 6

CType(Me.m_CalMain, System.ComponentModel.ISupportInitialize).EndInit()

Should this thread be running with this priority?  What can I do to lower this thread's priority back to Normal so that the application runs, responds and refreshes corrrectly?

Many thanks.

If the Calendar control's constructor is not creating the thread, what is the constructor doing that is resulting in a thread being created?  Because the thread is definately being created by something in response to what is happening in the Calendar control's constructor.  I've proved this by debugging my application and checking the threads list before and after stepping over the Calendar's instantiation.
