I use delphiXE+AlphaControls 8.14
The mainform has no effect when the AnimEffects.formhide.time set to 100 or other numer.
I have tried and found comment this line will solve the problem:
//Application.MainFormOnTaskbar := True;
if comment above,the FormHide AnimEffects will be activated .But the effect has problem which can not be described very exactly.Just Run the Exe and see it.
The MainForm will Flash two times while closing.
Attachments is the source and EXE.
