无法在Visual Studio 2008（C＃、. NET Compact）中用鼠标调整控件的大小

我正在Visual Studio 2008中为Windows Mobile 6开发Windows窗体应用程序。要求在每个窗体上具有一些通用控件，例如徽标（PictureBox），标题（Label）和简短说明（也包括Label）。我决定使用这些控件制作一个FormBase，并从该库继承其他表单。

问题是由于某种原因，当我在继承的窗体上放置一个Button或另一个控件时，无法使用鼠标调整其大小。我可以通过Shift + Arrow使用键盘快捷键来调整大小，但是鼠标不起作用。

这对我和团队中的其他开发人员来说都不是很方便。

有什么建议？

    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
