Hey I'm new to .NET and am working VB.NET... I have an application that that run from a module so the first form that would be seen is hidden in the system tray. There is a timer that when elapsed checks for a the existance of a file. When that file is found I would like to pop a form. The form pops fine on interval when the file is found but then once displayed seems to freeze up, i can still click the system tray icon for the first frame, nothing on the second messForm (message form) All messageboxes seen below are aids in seeing whats going on they all display correctly. Here is some code. Any ideas would be helpful!

Public Sub Timer_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles Timer.Elapsed
Try

If File.Exists(fullpath) Then
popMessageForm()
End If
Catch obEx As Exception
Throw obEx
End Try
End Sub

Public Sub popMessageForm()
dim messForm As New messageForm
MsgBox("popmessageForm start")
messForm.Visible = True
messForm.Focus()
MsgBox("before show")
messForm.Show()
messForm.Activate()
messForm.BringToFront()
messForm.Main()
MsgBox("end popmessage")
End Sub

Thanks for any help!

i failed to mention before that the popmessage() sub routine works in other areas of the project
::ex::

Sub Main()
...foo
popMessageForm()
...bar
End Sub

::works like i would like... something im missing about the timers.timer?
thanks

Solution found!

timer was as system.timers.timer not a System.Windows.Forms.Timer

using a system.windows.forms.timer_tick instead of system.timers.timer_elapsed event for a pop made the form not freeze. Thanks for the help.
