TreeView nodes collapse when from minimized

[bradles]

A VB.NET newbie using VS.NET 2005 beta 2,

Developing a small app with a TreeView, minimising the main form to the system tray and finding the treeview collapsed to the top most parent when the form is maximised.

Tried setting a variable to the last selected node and setting both tvw.SelectedNode to variable and EnsureVisible without success. In addition it seems the top most parent registers 0 for Nodes.Count when I step through the code.

Anyone come across this before or have any ideas?

Any ideas?

FYI,

After plenty of breakpoints and code stepping, discovered that the Node_BeforeExpand event for the TreeView was being fired at every minimise, hiding the taskbar and vice versa. Have some code in there to read some files & folders, so setting some conditions within the sub did the trick.

Is this a bug in VB.NET 2005 beta 2?
