Combo Box Will Not Drop Down

[sjf905]

Hello, I have a combo box on a form. When I run the application, I click the drop down arrow and it does drop but only for a split second, then rolls back up. If I click on the text of the box, I can key down to select anything in it. I have tried:

comboBox1.Enabled = true;
comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;
comboBox1.Show();
comboBox1.BringToFront();
comboBox1.Focus();

Both of these return false:
comboBox1.CanSelect
comboBox1.CanFocus

I've been programming for a while but am new to C#.
Thanks for any help.

Do you have code in any of the events raised by the combobox?

That would be the first thing I would check. you might be unintentionally sending the focus to another control, forcing the drop down to roll back up, among other possibilities.

No code that I made. I created it through the design interface and added the items likewise. Where could I check to see if I am unintentionally causing the error?

BTW, I have tested other combo boxes in other forms (totally seperate of this project) and get the same result.

Try another machine, sounds more like an OS or even a mouse gone wacky.

Figured it out!!! Finally. I have a skin on the application that I got from some website. Remove the skin, combo works fine. That took weeks...
