SecureCRT 5.1b4 disappears when clicked in taskbar

[renep]

When I start SecureCRT 5.1b4 and click it's icon in the Windows XP taskbar, the entire window disappears

The same thing happens when some other application has the focus, I click SecureCRT to call it to the front and by accident click the icon again.

In other words, when SecureCRT has the focus and receives a single click on it's icon in the taskbar, it disappears. With other applications, a (second) click when it's already active, minimizes it.

I find this quite annoying, since it's very easy to loose a vi editing session by accident.

Also, when SecureCRT is active and I do right mouse click (on the icon in the taskbar) > minimize, the window disappears.
