user control mouse

Hi Ive added a usercontrol to a form. When I hover over the control
with the mouse, it shows the timer icon, but my control is just a
layout and Im not actively updateting it. If I come of the control ten
I have the arrow. Im assuming that the timer meens that somethings
actively happening within my code. Any ideas as to what i should look
for. I am using a thread to update a treeview, which I use afterselect
to add the controls, but I think the thread should have finished
before the control gets added. I realise its difficult to advise
without the code, but is there a way to show if any threads are still
active.
Regards Robert

It sounds as though you may have created the UserControl instance in the
other thread. This would be a big no-no, and would lead to the behavior
you're describing. If that's the case, seeing if other threads are active
wouldn't help anyway, because the problem isn't that there's another
thread that's active, but that the thread that created the control is
either not around any more or is around but doesn't have a message pump.

Other than that, you're right...without an example of code, it's just too
hard to comment. The actual possibilities are too great in number to
reasonably narrow them down without seeing the code you're actually using.

Thankyou for your reply. Ive modified my code here so the control is
added when I click a menu item, the result is the same. I have a form
with, menustrip, tabcontrol showing one page with a treeview. I run
the form, click menuItem which adds a tabpage with the control.
private void eventsToolStripMenuItem_Click(object sender, EventArgs
e)
{
TabPage newPage = new TabPage("robs");
tabControl1.TabPages.Add(newPage);
tabControl1.SelectedTab = newPage;

MarketViewRow row = new MarketViewRow("rob");
row.Name = string.Format("{0}", 2222222);
row.Dock = DockStyle.Fill;
tabControl1.SelectedTab.Controls.Add(row);
m_marketViewRows[row.Name] = row;
}
my control:
public class MarketViewRow : System.Windows.Forms.UserControl
{

public PointPairList Backodds = new PointPairList();////graph

Thankyou for your reply. Ive modified my code here so the control is
added when I click a menu item, the result is the same.
Click to expand...

If you want more help, you need to post a concise-but-complete sample of
code. The sample you posted was incomplete (at a minimum, it doesn't
appear to include your toolstrip, to which the handler is apparently
attached), and it's also not concise: it includes a LOT of stuff that
surely has nothing to do with reproducing the issue.

When you have take the time to pare down your code to the absolute minimum
required to reproduce the problem, post _that_ minimum example. Hopefully
someone will be able to point out a way to fix it then. With what you've
posted now, that's not going to happen.

Pete
