BUG:About Tasmanian Traders Dialog Disabled System Info Button

The information in this article applies to:

• Professional Edition of Microsoft Visual FoxPro for Macintosh, version 3.0

SYMPTOMS

The About Tasmanian Traders dialog invoked from the Help menu in the TasTrade sample application will zoom and reveal a disabled System Info... button. The About Tasmanian Traders dialog can be zoomed either by double- clicking the title bar or by using the zoom box in the upper right corner.

In Visual FoxPro for Windows, the About Tasmanian Traders dialog is not resizable and cannot be minimized or maximized. In Visual FoxPro for Macintosh, this dialog can only be maximized or restored to its original size once it has been zoomed.

CAUSE

The Zoombox property in the Aboutbox class of the About.vcx file is set to TRUE (.T.). The System Info... button was not implemented but it was not removed from the Aboutbox class. In Visual FoxPro for Windows, this button is not seen because the About Tasmanian Traders dialog cannot be maximized.

WORKAROUND

Do not zoom the About Tasmanian Traders dialog. Or, go into the Aboutbox class, change the Zoombox property to FALSE (.F.), and rebuild TasTrade.app. If the Zoombox property is changed to FALSE, the About dialog will not be zoomable.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
