有时候，当我们在Microsoft Dynamics AX 2012 中打开新窗体时，新打开的窗体没有变成当前窗体，而是位于工作区窗体的后面，必须手工点击切换，使得操作非常不方便，下面这篇博文解释了发生这种情况的原因和预防办法。
In Dynamics AX 2012, when you open the forms, you might see some of them open behind the other forms. User may get the impression that the form was never opened. This happens if the form opened slowly; a cold start, uniqueness of the data including large number of records or complexity of the form may cause the form to load up slowly. The form hide behind the other form because of Windows’s ‘ForegroundLockTimeout’.
Doing the following changes to your system could fix this issue. Since it involves changing a registry key in your system, take necessary precautions.
Create a Restore point before performing the steps below as a precaution.
